Studio Electronics Tonestar 8106 Synth Voice Module (black)
TONESTAR 8106, an ARP 2600-inspired complete synth voice, 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 Tonestar 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'.
27 Knobbed and "Shafted" Potentiometers:
VCO: RANGE, PM MAN, LFO, PORTA, MOD (ENV), TRIANGLE, SAW, SQUARE, SUB, TUNE; Noise: LEVEL; VCF: FREQ, RES, KBYD, DRIVE, HPF, ENV, MOD (LFO); LFO: AMNT (OSC), RATE; ENVs: (ADSR) ATTACK, DECAY, SUSTAIN, RELEASE, (AR) ATTACK, RELEASE; VCA: FEEDBACK (filter / VCA), VOLUME
6 Switches:
VCO: OCT (up / null / down); FREQ / PW (frequency / null / pulse width); NO VCF (VCF / null / no VCF); VCF: TRIANGLE / SQUARE (triangle / null / square); ENVs: HOLD, MSTR (hold / null / master); VCA: IN / MIX
21 Jacks:
VCO: TRIANGLE, SAWTOOTH, SQUARE, MIX, 1V / O, MOD IN; NOISE: NOISE (white); LFO: DEPTH, TRIANGLE, SQUARE, SPEED; VCF: EXT IN, FIL OUT, MOD IN; ENVs: MOD IN, ADSR OUT, AR OUT, GATE IN; VCA: IN / MIX, VCA IN, OUTPUT
- PCB Mounting Scheme: Through-hole
- Filter: A 6db / oct hi-pass filter followed by a recreation of the Roland IR3109 module, which is a 4 pole, 24 db / oct voltage controlled lowpass filter with voltage controlled resonance. 3 dual OTAs with similar topology to the BA662 used in the Jupiter 8 (and the IR3109 module) were employed, 1 amp for the hi-pass filter, 4 (with added buffers) for the low-pass, and 1 for the resonance. This filter takes a wide range of input signals, and tracks control voltage extremely well. Tap points are available for 6db, 12db, and 18db / oct. Although the topology is similar to the 4072, the tonality, especially when over driven, is distinct.
