Oberheim OB-1 Analog Synthesizer

Good Condition and recently gone through by a local tech who also installed the a new Tauntek programmer with the following updates:

A new MCU-based programmer pcb is now available for the OB-1

I have designed a replacement for the Oberheim programmer with the following features:

1) 64 programs in 8 banks of 8

2) Programs are stored in non-volatile EEPROM. No battery needed.

3) After a program is loaded, only controls that have moved are "live", so patch editing is now possible.

4) Manual mode forces all controls to be "live".

5) Optional (non-volatile setting) periodic flash of current bank selection

6) Optional (non-volatile setting) quantization of coarse freq for oscillator 1 to octaves

7) Comes with 24 pre-programmed patches, which can be over-written later if you chose

8) Smaller pcb mounts on four of the existing standoffs, providing better access to pcb underneath

9) Implemented connectors are the same as original programmer for easy installation

10) All IC's are socketed. All components are through-hole.

11) 20-turn trimpot for easier one-time oscillator tuning adjustment

I installed new key bushings as well in the last month.

Outer case has some blemishes and surface rust here and there, but in overall good cosmetic condition.

Pretty rare piece and would make a great addition to your studio or collection.

Info from vintagesynth:

The OB-1 is a simple and great monophonic synth from Oberheim based on the same synth architecture as the SEM. Released in 1978, it was the first truly programmable analog synth of it's time with 8 program memories.

Classic and fat sounding bass & lead synth sounds. Similar in sound and synthesis from the Roland SH-101 to the MicroMoog. It has two analog oscillators and a very capable 2 or 4 pole switchable VCF (filter) that sounds great, and a good LFO that can control the VCA or VCF. This is a very versatile monosynth, especially during its time, and makes an interesting alternative to other more common bass-synths.
