Buchla - 208C

In principle, the 208C offers the same synthesis architecture as an Easel. However, it is a compact module and there are even some new features waiting to be discovered.

New features compared to the previous 208C:

• MIDI input(USB B/DIN) optional
• MIDI A (USB Host) optional expansion port.
• Five additional audio connections to get independent inputs and outputs from the oscillators and the gates, plus an FM input to the modulation oscillator.
• Five additional banana CV connections to control knobs and faders and ability to send pulses independently to different inputs.
• If no aux input is present, analog white noise is generated (using the 266 circuit).
• A more logical layout of of the top row.
• A power/control mode LED indicator.
• Pulser now has a dedicated single pulse switch and mode distinction
• The modulation oscillator section is now green, so that each main section has its own color.
• The listed oscillator frequencies are more accurate and the scaled fader input range is trimmable from the old range to 1.2v/oct.
• You can trim the new modulation oscillator and envelope generator inputs to work with the typical input ranges you desire.
• You can trim the oscillators to your desired volts per octave range for both the keyboard and the fader inputs. 
• You can also reduce the gain on the gate 1 input if you have an unusually hot, non-Buchla input.
• One single circuit board allows it to be modular case friendly and easier to service; the 208c module can fit into a 200e case.
• Switches and jumpers for those who want to use the new banana inputs —those for the modulation oscillator and sustain— to control the sequencer stages instead. 
• Standard headers for the program card connector that allow us to develop future iProgramCard-like preset control from inside the unit.
• New connectors allow Buchlas plug-in MIDI interface and provides an optional stereo digital fx option (coming as an optional add-on in the future)
• Actual stereo. The 208 was always a mono synth, but if you plug in a stereo digital fx (coming as an optional add-on in the future), you’ll get stereo outputs on the MIX OUT and headphones.
•  A new power connector for more cable length and case flexibility and removability and one that’s already compatible with the more recent revisions of the Easel power board.
