Emulation of features, functions and appearance of ARP Odyssey and simulates many of the more popular mods for it. Built with Synthmaker, so the actual sound does not match that of Ody - but for the many folks who will never be able to afford the real thing, this allows playing in a similar sandbox for free.
- Square>Sine>Saw Third Oscillator.
- Second LFO, similar to the one in the ARP 3620 keyboard, but with Saw added.
- Five VCF Modes.
- VCOs' waveforms cross fade Sine>Peak>Saw and Sine>Tri>Pulse.
- VCOs' Freq mod inputs can switch to Phase Mod.
- Bottom positions of mod input switches can select any CV source.
- Envelope times can be tripled. Can be switched to A/D Loop mode.
- LFO Rates can be multiplied by 10 or 1/10.
- Filter Feedback on a dedicated slider.
v1.0.2 - corrections to waveforms' polarities and phase. Sub Osc now affected by VCO 2's Frequency mods. S/H Mixer inputs can select any CV source. Saw added to LFO 2. Ring Mod can be AC or DC, as with ARP 2600. Poly/Mono/Legato modes. MIDI CC added as CV source. VCOs' course tuning changed from octave switching to 'Semi' (+/- 48 semitones) or 'Freq' (free-tuning, like hardware; equivalent to +/- 72 semitones).
32-bit, so will require jBridge, etc., (or a DAW that will bridge) for use on 64-bit systems.
The link on the website is to a Sync.com folder that also contains the .osm Synthmaker source 'schematic', so anyone with SM, or it's successor Flowstone, can alter it to suit. It's hoped that anyone who makes significant improvements will share the result with everyone.
As this was originally built for my own use only, there are no presets included; I wanted to come at the instrument anew each time, as one did with vintage analog hardware.
"tonus", by the way, was ARP's original company name before being changed to Alan R. Pearlman's initials.
