Brooks is a 4hp thru zero oscillator. It still packs in a lot of features but will work better in most cases as the 2nd and/or 3rd oscillator in the system. Key features:
- Thru zero FM oscillator
- Tuning switch enables ranges of 0V, 3V, and 6V
- Tuning knob offers 4 octave range, when coupled with the switch you get a full 10 octaves.
- Both hard sync and time reverse (soft sync)
The chip used for the core of this module is the SSI2130, which has a tendency to lock up on startup when the power rails come up asymmetrically, which is most common in Intellijel power supplies. I did my best to fix this but there may still be instances where the unit locks up on startup. If you end up in this state, just flip the LFO/VCO switch to get it behaving.
