ARPÂ® 2600-inspired Eurorack Modular Synthesizer with Arp Filter
TONESTAR 8106, an ARPÂ® 2600-inspired complete synth, infuses Tim Caswell's "Jupiter to Juno" filter alchemy,a 6db/oct hi-pass filter followed by a recreation of the Roland IR3109 module,into our Tonestar 2600 platform; this chirpy yet full-bodied 8106 model is also fully #OutsToOuts modular featuring 27 pots,one more that the 2600 model for the high-pass filter, 6 switches,one less, sacrificing resonance modulation for that high-pass filtering, and 21 jacks. If the Tone 8106 thins somewhat with resonance excess, route the triangle wave 'round the VCF with the "NO VCF" switch setting, and keep this juicy reimagining of the Roland® IR3109 module boomin' and gloomin'.
"The VCO is the same affair as the Oscillation, the Boomstar, and the Omega. It's kind of a combination of ArpÂ®, OberheimÂ® and MoogÂ® circuits (sort of a greatest hits), time-tested, very stable,very good tracking over a very large range; certain parts have to be hand selected to achieve that level of exacting performance. Editors Note: This module is a TONESTAR,its own thing,and not a 2600 clone attempt; nevertheless, the Tone tugs lovingly at times on the sleeve of the 1970's era classic. Envelope FYI: The Tonestar Sustain control replicates the behavior of the 2600 and Odyssey: after the initial Decay, it continues to move (sink) very slowly, adding a little extra texture to the sound. It's technically a flaw, but after digging out my Odyssey, it is for sure a desirable "quirk", and the perfect companion to the 4072 filter (which we mistakenly titled a 4075 in the Boomstar Modular line).Another bit of fun: The LFO is voltage controlled, so you can envelope, LFO, or otherwise modulate both the rate and the depth; the ADSR amount is also voltage controlled, so it can be manipulated by MIDI dynamics, MIDI volume, an LFO, etc.
