Living feedback and FM synth
Organism 8 is an attempt to recreate the structure of the Soma Labs Lyra 8 designed by the brilliant Vlad Kreimer. It is an eight-voice synthesizer that excels at less-traditional synth sounds due to its cross-modulation design.
This instrument does not function like a normal synthesizer. There are eight voices that are activated by the white keys on a keyboard from C2 to C3. No other keys will function.
All of the controls have tooltips - use them to get a better understanding of the synthesizer, or refer to the Lyra-8 documentation.
- Added "PT2399" button. This adds some more character to the delay. The Lyra 8 uses two PT2399 digital delay chips. These common chips are known for adding noise at longer delay times. Noise has been purposely added in: longer delay times = more noise, same as on the original Lyra. This switch also adds slight distortion and band limits the delayed signal. The original cleaner delay is still available.
- Added two more snapshots.
- Fixed a bug where voices 7 & 8 were not getting FM in correctly.
- Changed the way the oscillator shapes are mixed in order to keep more even volume during the transition from triangle to sawtooth when using the Sharp control.
- Added a white “B” panel for people who aren’t a fan of the magnificent green shade of the original.
The following are differences from the original Lyra-8:
- The synth has a full stereo path. The stereo panorama is created by the added pan controls for each individual voice.
- Inputs are velocity sensitive, which helps add some of the expressiveness lost from the lack of contact pads.
- The Sharp control smoothly fades through three waveforms, the original soft triangle and square waves with a sawtooth in between.
- Added individual drone knobs for each voice, breaking out the controls that are set to groups of four on the Lyra 8.
- Added a Slew function to the LFO. Rather than just using a triangle output for the LFO, this changes the transitions from high to low into ramps while maintaining the sustained portion of the signal. Note that this will cause the amplitude of the LFO to be reduced at high slew rates. This setting is shared between the modulation of the VCO pitch and the delay lines.
- Changed the Vibrato control from a switch to an attenuator, allowing for more subtle applications than the original binary switch. The vibrato retains the slightly different timing for each bank of two voices.
- The Delay will self-oscillate when the feedback knob is on full. You’ve been warned!
The knobs are from the very useful 008 and 002 knob kits made by Efflam Le Bivic, be sure to check out his great work.
