How do you do a chiptune?

1. Native Instruments Massive

More Info & Price (Trial Available)

Massive is a hybrid synthesizer by Native Instruments. It’s one of the most iconic synthesizers ever created for electronic music.

Massive needs no introduction to anyone creating electronic music. It’s a hybrid synthesizer famous for utilizing wavetable and virtual analog synthesis. The oscillators in Massive, along with some of the waveshapes and wavetables they include, are ideal for chiptune, since they perfectly capture its 8-bit characteristic sound.

Key Features:

• Oscillators
  The oscillators inside Massive are true powerhouses of synthesis. The oscillators can morph from one waveform to another, known as wavetable synthesis. It enables a broader range of sound design possibilities since one oscillator can create thousands of sounds with a single wavetable. It’s also one of the reasons why Massive is perfect for chiptune music. You can get accurate chiptune sounds by modulating the wavetable position, especially on wavetables like the Additiv series or the formant series. Each oscillator comes with pitch controls, a wavetable position knob, an amp knob, and an intensity knob which controls the amount of the oscillator effects. The oscillator effects are another creative way to achieve chiptune sounds, either through the FM effect, Spectrum effects, or ring modulation.
• Filter
  There are two filters included in Massive. They can be set in serial or parallel modes or a mixture of both. You get 11 filter modes inside Massive with classic options like two pole highpass and lowpass filters or bandpass filters. Some more creative options include lowpass Daft, a tribute to the famous French filter found in Daft Punk records, comb filter, and scream. The filter has a cutoff knob and a resonance knob which sounds excellent when set on high amounts.
• Modulation
  The modulation system is Massive’s crown jewel, without a doubt. There is no modulation matrix on board. Instead, you get a modulation system that allows any parameter to be modulated while keeping everything clean and neat. Every parameter has small boxes underneath representing empty slots for modulators to be inserted. You create a connection between the modulator and the target once you drag an LFO or envelope into the empty box. Each modulator is color-coded, with LFOs green, envelopes blue, and macros yellow. This small detail keeps the complex modulation routings making sense even in the most complex patches. There are four LFOs, four envelope generators, and eight macros. The LFOs can be set in LFO mode, stepper, or performance mode. The latter options are perfect for creating arpeggiated riffs, evolving textures, or complex rhythms.
• Effects
  The effects inside Massive are simple but effective. You can run three effects in a single patch, one of them being an EQ which is always running. The effects include options like Delay S, which comes with separate left and right controls for stereo effects, reverb, C tube, which is particularly useful for chiptune sounds, dim expander for exaggerating a sound’s stereo information, phaser, chorus, classic tube, tele tube, and Brauner tube, which is one of my favorite distortion effects.

Compatibility:

Massive is available on Windows 10 or 11 and macOS 10.15, 11, or 12 in VST, VST3, AAX, and AU formats.

Summary:

Massive is an iconic synth, perfect for most electronic genres, including chiptune. The oscillators and complex modulation system will complement the 8-bit sound of chiptune music perfectly. At the same time, effects like Brauner tube and C tube will ensure your chiptune sounds are crisp and high-frequency dominant.

2. UVI 8-Bit Synth

More Info & Price

8-Bit Synth is an 8-bit synthesizer designed by UVI.

This synthesizer is inspired by the lo-fi hardware sounds of yesterday and consists of a dual-layer engine loaded with authentic hardware samples. This is where the beauty in its approach lies: unlike other synths on this list, it doesn’t emulate sound chips from the 80s but instead samples them.

Key Features:

• Extensive sound library
  8-Bit Synth comes with an extensive sound library sourced from hardware synthesizers and game consoles of the past. UVI sampled all sorts of hardware, including the Commodore 64, Game Boy, SID Station, and Mod Machine. Overall, 375 high-quality synth patches are organized in a menu split by sound categories. The categories are brass, bass, chip mod, chords, composite, drums, fx, keys & bells, leads, pads, plucks, polysynths, sweeps, and waveforms. If you wish to know how 8-Bit Synth works, it’s divided into two layers. Layer one plays sounds from the SID Station, and layer two sounds from other hardware.
• Modulation
  There is an amplitude envelope and a filter envelope inside the main page of 8-Bit Synth. They can affect each layer individually or both of them. The amplitude envelope is an ADSR-style envelope with velocity and attack toggle switches. When you turn them on, the velocity will affect the attack of the envelope, meaning the bigger the velocity, the longer the attack. The filter envelope is also an ADSR envelope, with a depth fader determining the modulation amount. Finally, a balance fader determines the balance between the synth’s lower and higher frequency register. If you move it to the left, the lower register will be more emphasized, and vice versa.
• Edit
  The edit page lets you adjust the vibrato, tremolo, or filter control. By adjusting them, you automatically map them to the mod wheel. All three can be turned on and mapped to the mod wheel simultaneously. Next, you can adjust the layers’ polyphony and set them to mono or poly. Afterward, you can add portamento or glide. Next, you can adjust the pitch of the layers up or down by octaves or semitones to create more complex compositions. Finally, you can add stereo effects by enabling unison or detuning to sweeten and thicken the instrument’s tone.
• Sequencer and LFO
  The modulation possibilities inside 8-Bit Synth don’t stop at the envelopes. A sequencer under the mod panel can modulate the volume and filter of each sound layer. You can set it, so it modulates either or both sound layers. In addition, you have control over the number of steps, speed, delay, and smooth parameters of the sequencer. Finally, there is an LFO in the same panel for modulating the volume, filter, and pitch of either or both sound layers. It comes in sinewave, square, triangle, and step & hold shapes.
• Effects
  8-Bit Synth has an effects page loaded with seven effects: EQ, thorus, phasor, sparkverb, drive, ensemble, and delay. Thorus is a chorus module designed by UVI with speed and depth controls. The ensemble is perfect for thickening your sounds and adding a 3D feel, while the EQ effect is interestingly rich and versatile. The sparkverb is probably my favorite of the bunch. It has a rich sound and independent low and high-frequency controls for cleaning up your sound. It could easily be a standalone effect VST.

Compatibility:

8-Bit Synth is available on Windows 10-11 and macOS 10.14-12 in VST, VST3, AAX, AU, and Standalone formats.

Summary:

8-Bit Synth is an exciting and captivating plugin. One thing I haven’t touched on yet is the gorgeous user interface. It’s very inviting and easy to understand, something that makes it perfect for both beginner and experienced producers.

The sound layers and the sound library are excellent and will keep you inspired for days, the effects are stellar, and the modulation system steals the show. Overall, this is an excellent synth for producing chiptune.

6. AudioThing miniVerb (Chiptune Echo)

More Info & Price (Trial Available)

miniVerb is an 8-bit chiptune and lofi reverb plugin designed by AudioThing. It’s designed similarly to miniBit, the synthesizer we covered above.

miniVerb is inspired by the sound of games consoles and retro computers. It recreates the reverb sound of early game consoles, which achieved a sense of space by playing a delayed version of the dry signal, effectively creating a slapback effect. Of course, this was later developed into traditional reverb effects, which miniVerb covers beautifully.

Key Features:

• Echo
  The main engine of miniVerb is the echo section. Here you can recreate vintage reverb effects by using a single echo engine. Producers and engineers of the past added space to their sounds by either playing back a delayed version of the dry signal or multiplying the number of playback signals to create longer delays resembling the reverb sound. You can recreate the former effect by using zero feedback, short time, and mono width. To recreate the latter, you must play longer times and add feedback. Finally, for a more modern sound, you can increase the width and enable double time, which lies in the blue button on the top left corner of the echo section.
• Color the sound
  miniVerb includes two filter units to help you color the sound and achieve the perfect reverb tone. The first filter is labeled as a pre-filter and is first in miniVerb’s processing chain. You get to roll off high frequencies before any processing is applied to the sound. The second filter is a post filter and rolls off high frequencies after the echo or reverb sound has been added to the mix. The filters can be switched from lowpass to highpass and turned on or off.
• Vibrato
  The vibrato engine offers an additional flavor that pushes the sound further into lo-fi territories. It adds pitch modulation on the wet signal that emulates pitch flutter from old-school tape machines, although it can be exaggerated if you want it to. There are rate and depth knobs to fine-tune the effect and an on/off toggle switch.
• Crusher
  The crusher is the most chiptune-appropriate feature of miniVerb. It has three knobs: bits, downsample, and shifter. The bits knob adjusts the bit rate of the sound and has a range of 2-24 bits, the downsample adds a bit crush effect, and the shifter is a pitch shifting effect. The bits knob is handy in a chiptune setting and gets gnarly and noisy the lower the setting you choose. The shifter is probably my favorite control since it allows for the most creative and leftfield results. You can create trippy harmonies or modulate them for some psychedelic results.

Compatibility:

miniVerb is available on Windows 7 or higher and macOS 10.9 or higher in VST2, VST3, AU, and AAX formats, 64-bit only.

Summary:

miniVerb is an exquisite retro reverb and delay unit by AudioThing. The sound is accurate to the retro video game sound era and is excellent for lo-fi and chiptune.

The echo is versatile and can achieve a wide range of effects, and the addition of vibrato and crusher modules is an addition to fresh air. I highly recommend this for all chiptune producers and producers interested in lo-fi, psychedelic music, and any genre that tries to achieve a retro sound.

5. Matt Montag NES (Nintendo VST)

More Info & Download

NES is a free synthesizer designed by Matt Montag.

NES is designed to emulate the Nintendo 8-bit sounds by emulating its 2A03 chip. Montag built the plugin in Outsim SynthMaker to ensure a high-quality user interface while producing alias-free primitive waveforms.

Key Features:

• Nintendo-accurate waveforms
  It’s not an easy feat to recreate a sound as iconic as that of Nintendo. The hardest part to get right is the pure waveforms that have such a memorable feel to them. For example, to achieve the distinct sound of the Nintendo triangle, NES’s creator used a single triangle waveform that’s quantized to 16 discrete amplitudes. This ensures a curved falling segment of the waveform and a linear rise, something that produces even more harmonics. Another thing NES gets right is the noise channel, which sends a random sequence of bits to audio out. The bits are then subdivided to create eight unique output samples that are then merged and lowpass filtered to create an 8x oversampled alias-free output.
• DPCM
  DPCM stands for Delta Pulse Code Modulation, one of the processes that give Nintendo its unpredictable sound. NES achieves DPCM by increasing or decreasing the signal amplitude at fixed intervals on a per sample basis. NES uses DPCM to play back sampled audio and does so in code. This allows the user to choose custom WAV file samples with DPCM in real-time.
• Modulation
  Four panels can be modulated inside NES: volume, pitch, fine pitch, and duty cycle. These parameters can be modulated with independent LFOs, which can be synced to the host or run freely. There are also color-coded visualizer windows for you to monitor the LFO shape and how the modulation affects the sound.

Compatibility:

NES is available on Windows only as a VST plugin.

Summary:

NES is one of the most accurate emulations of the iconic Nintendo sound. The sound of the instrument is characteristically 8-bit and perfect for chiptune. The purity and detail of the oscillator waveshapes are impressive and make owning this instrument a no-brainer.

  Fernando Lachari sampled the Commodore chip in his Proyecto Return laboratory through a Yamaha 01V Mixer and into an Echo Mia sound interface. This attention to detail ensured a high sound quality with drum sounds in their purest form. Overall, the sounds accurately depict the original chip’s character, and their tone is ideal for chiptune and 8-bit music.
• Varied drum sounds
  T.Rex 64 comes with a variety of different drum sounds to accommodate all your percussive needs. There are eight kick drums, eight snare drums, two toms, one cowbell, one clap, and two hi-hats.
• Utilities
  Apart from the collection of drum sounds and the accompanying drum pads to perform them, T.Rex 64 includes a few parameters to control the overall sound. There is a single reverb knob for adding space to your drums. The reverb is lo-fi and on the same page as the low-fidelity drum sounds. There is also a panning knob and a volume knob to control the overall balance of your mix.

Compatibility:

T.Rex 64 is available on Windows and macOS in VST and AU formats.

Summary:

T.Rex 64 is a straightforward plugin that delivers precisely what it promises. The drum sounds capture the spirit of Commodore 64 and are perfect for chiptune production.

Although a few more drum sounds and parameters would be appreciated, the overall sound quality and no-cost nature of T.Rex 64 make up for its shortcomings. 

7. Futurecraft Kairatune (Versatile Synth With Chiptunning in Mind)

More Info & Download

Kairatune is a free synthesizer designed by Futurecraft.

Futurecraft created Kairatune to produce crisp electric sounds suitable for all genres of electronic music. They say that Kairatune is created for the demanding producer willing to push a synth to its limits.

Key Features:

• Oscillator
  Kairatune has a single multi-oscillator. It comes with sawtooth and square pulse waveforms, and although it’s packaged as a single oscillator, it has the sound of five single oscillators. There is a low knob for blending in a lower octave tone, a spread control for adding stereo depth, a phase knob, and a detune menu. The oscillator sounds excellent and can produce all sorts of sounds, from dreamy plucks and pads to harsh bass sounds and infectious lead synths.
• Modulation
  Multiple LFOs and envelopes inside Kairatune help you push your sound design ideas to their maximum limits. Almost every section of the instrument’s interface has an LFO or envelope attached for modulation. For example, there are lowpass and highpass filter sections that can run simultaneously and have independent LFO and envelope controls. The LFOs and envelopes are synced to the host tempo and can achieve some very interesting rhythmic results.
• Effects
  There are three effects inside Kairatune to help you polish your synth sounds. First, the delay is one of the most advanced I’ve ever encountered on a free synth. It is a stereo delay with left and right controls for fine-tuning your stereo field. There are also high pass and band pass filters inside the delay, which add another extra layer of excitement. The phaser has depth, rate, and feedback controls and can help you achieve even more intricate stereo effects. Finally, the EQ has two bands with various shapes to help you clean up the frequencies of your patch.
• Easy to learn
  Considering the number of features and sound design possibilities Kairatune is capable of, the interface is very clean and well designed. Everything is located on the same panel, and there are no hidden windows, ensuring producers of all experience levels can feel at home instantly. There’s also a nifty color-coded system for the modulation controls, where LFOs are green and envelopes blue while all volume values are purple. It’s just a little detail that keeps Kairatune easy on the eyes and understandable, especially on complex patches.

Compatibility:

Kairatune is available on Windows and macOS in VST and AU formats.

Summary:

Kairatune is one of the most intricate free synthesizers I’ve seen. The oscillator is excellent, and the amount of modulation options is staggering. The delay effect is one of the most advanced in a free synthesizer, and the interface is excellently designed.

I’d recommend this to all advanced producers who wish to have a synthesizer that makes sound design enjoyable and effortless. It’s truly a sound designer’s paradise. Finally, its electric nature and focus on electric sounds make it ideal for chiptune.
