A190 Midi-CV-Interface CV1 has 12 bits resolution especially for VCO pitch control. CV2 has 7 bits resolution for control applications (eg VCF, VCA, etc.) Gate output: + 5V to +12 V-trig, S-trigger. MIDI-to-gate-clock: synchronizing for instance, volt swithes, ADSRīs or sequencers. Possible to divided down to provide a variety of clock outputs. Reset Output: MIDI Start/Stop continue. Portamento (glide) and pitch-bend. In-built software LFO. All control parameters can be saved in non-volatile memory. |

A191 MIDI-CV-interface/Shepard
Generator. Most of the controls, indicators and in/outputs have a double function; there is a switch which toggles between the two sets of functions. MIDI-CV interface: 13 of the 16 control voltage outputs are dedicated to sending voltages converted from a particular MIDI controller (Mod Wheel, Volume, Pitch Wheel, Aftertouch, etc.). Controller messages on your chosen MIDI channel are converted into voltages in a range from 0 to 5 V. The other three sockets output an internal LFO generated in sync with MIDI clock, in three waveforms: sawtooth, triangle and rectangle. Shepard Generator: the sockets output eight different phases each of a triangle and sawtooth wave. In combination with other modules (VCO's, VCF's, VCP's, VCA's, Mixers) psycho-acoustic so-called Barberpole effects like never ending rising (or falling) phasings (with VCPs), filterings (with VCF's) or tones (with VCOs). To create the Barberpole effect you need the required additional modules in your system. For a good Barberpole effect we recommend a minimum of 4 VCP's (or VCF's or VCO's) and 4 VCA's (linear types A-130 or A-132). With 8 modules instead of 4 the sound becomes more smooth and tight. All A-191 settings can be saved into non-volatile memory. |
