Erica Synths Hexinverter Mutant Clap

TR-909-style old school clap drum module - eurorack format

• "909-style" clap with many more options than the original: more range, more depth
• Percussive synthesis engine + voltage controllable LFSR noise oscillator
• Noise pitch control: from clean 909 claps to "broken" and alien timbres
• NOISE + PITCH CV output: usable as a Commodore 64-style noise VCO
• Internal reverb derived from clap tone, with fully controllable decay via CV
• External input to synthesize clap from any audio source
• DRIVE from clean to extreme overdrive + bandpass filter cutoff control
• Reissue redesigned by Erica Synths in collaboration with Hexinverter

Erica Synths Hexinverter Mutant Clap

The iconic clap sound of the TR-909, but with all the features we would have wanted on the original. The Mutant Clap expands the classic "old school" character by adding a much wider tonal range: it is both a powerful percussive synthesis engine and a voltage controllable LFSR noise oscillator.

More range and more control: from 909 "vanilla" to sound design

Pitch control over the noise generator opens up possibilities ranging from the classic 909 clap to broken sounds, chiptune, and "alien" textures. Thanks to the NOISE output and PITCH CV, the module can also behave as a retro-flavored noise VCO (Commodore 64 style).

Internal reverb, external input and drive: timbre that is always sculptable

The Mutant Clap integrates an internal reverb derived from the clap tone: the decay of the reverb coincides with the decay of the sound and is fully controllable via CV, from short "snaps" to long, enveloping tails. You can choose between internal or external noise source for reverb generation, resulting in very creative combinations. The external input also allows you to "build" clap from any audio source.

Reissue with Erica Synths Support.

After the closure of Hexinverter Électronique (announced in September 2022), Erica Synths has continued the life of some iconic modules: retaining the functionality, redesigned the hardware in close collaboration with Hexinverter, and providing support for reissue versions.
