SEEDS is a complex powerful 8 bit oscillator and can be used as a complete synth voice.
Probably the most interesting thing about modular synthesizers is how we can try new things and get unexpected results. This is especially nice in live improvisations, but modular can be a bit slow here – patching up about four or five modules to get a simple melodic sound takes a lot of time when you have a musical idea right now. Seeds allows you get a sound playing quickly, that you could then tweak and extend.
The waveforms in SEEDS are inspired by digital synthesiser sounds of the 90’s. There are two reasons for that. First of all; those sounds are a natural match for the rather modest Atmel chip on the Arduino Nano. That music was made using digital synthesizers using the processors available at the time, and those had to make the most of the chips available at the time, which were quite comparable to the Nano. The second reason is that those sounds are a lot of fun. Once that link became clear it became more a of a guiding principle than a limitation; it seems more sensible to lean into such links than to resist them.
Seeds features the following algorithms:
- The original “Grains” sound. Two triangle-wave formant peaks synced by the main oscillator. The “mod” knob sets a formant peak.
- Triangle wave with wave-wrapping. The “mod” knob sets the amount of wave-wrapping.
- Super-saw, featuring three detuned saw waves with a PWM feature modulated by an LFO.The “Mod” knob controls the LFO rate.
- Classic FM; a “carrier” sine wave phase modulated by a second sine. The “mod” knob sets the modulator wave’s pitch offset.
- Saw-wave with hard-sync.
- Tuned noise
- Square wave with pulse-width modulation and built in LFO. The “mod” knob controls the LFO rate.
Ginko Synthese are planning future firmware updates to add new modes.
