this is a special sequencer generating a modulation signal. most of my synths and samplers have a cv-input where you can connect this one.
the basic concept is similar to the performer-modulation in N.I.'s Massive. you can select 16 different curves which are written into the 16 sequencer steps. you can scale each sequencer step and also adjust the overall level of the modulation signal.
the instrument corresponds to incoming midi note, gate and control messages. you can select one of eigth patterns using midi note C2 - G2. The sequence restarts at incoming midi gate signals or at the snc-input if "gate sync" is activatetd. last but not least the amount knob and the invert-button correspond to midi control # 1 and 2.
the mp3 file is played by my nord synthesizer with a plasma sequencer for gate and pitch and a MS16 modulating osc 1 fm amount and filter 1 frequency.
