Reason CV to MIDI to Oberheim Xpander
Reason MIDI Sequence routed as CV over Audio to an Oberheim Xpander. The Xpander is a six-voice desktop version of the Matrix 12 with which it shares an identical voice architecture. In many ways they are the most flexible non-modular analog synths ever built. Each voice has five LFOs, each with about five different wave shapes, plus the ability to sample most other modulators; five envelopes that can repeat themselves, sync to an LFO, and so on; a lag processor (like portamento, but more general); three tracking generators (that apply a series of linear functions to a value over its range); some ramp generators (the attack portion of an envelope); a 15-mode filter and a user interface to make all of this accessible.
This is kludgey. Here’s the data patch:
1. Reason MIDI Sequence to a Thor
2. Thor Converts MIDI to Control Voltage Note and Gate signals.
3. CV Note/Gate are converted to Audio Signals and routed to Hardware interface audio outputs.
4. Audio Outputs are directed to Soundflower
5. CV as Audio routed through Soundflower into MaxMSP
6. MaxMSP converts CV as Audio to MIDI
7. MIDI directed to a hardware port on a Novation controller
8. MIDI cable to the Oberheim Xpander
9. You cut a hole in the box
Because this configuration does not use Rewire, Audio from the Xpander can be recorded back into Reason. There is, however, a considerable amount of latency.
