Description | The Tom Oberheim Synthesizer Expander Module with Patch Panel has the one-of-a-kind majesty of the original Oberheim SEM analog sound, with incredible flexibility and sonic characteristics.
All internal SEM connections are brought out to 3.5mm minijacks. The basic connections are a one-volt-per-octave VCO control voltage and a standard 0 to +5 gate signal. |

| Velocity |
As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. |
Aftertouch |
Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel. |
| Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise. |
