via this auction.Details:
"Four oscillators, three multimode filters, two A/R envelope generators, digital gate sequencer, noise generator, phase shifter, external audio input...but no CV control. Uses mini-banana jacks.
You cannot control the pitch from an external controller as of now. They were not designed for that. You can control the frequency manually.
Also...you can run audio through the filters and even do some sort of weird sonic destruction by patching the fuzz output into the same input as the audio source. There are many many routing capabilities.
The HSL-II has 3 sine wave generators, a square and saw wave fuzz generator (awesome!), and a pink and white noise generator. These can be seen clearly on the far left of the HSL-II. The signal path flows from left to right and is patchable with mini-banana cables (included in the auction). There are 3 filters which allow patching through hi/lo/mid pass sections.
There is a phase inverter, limiter, frequency counter (with a classic red LED display) , 4 attenuators (volume), 2 mixer sections, a VU meter, and a few mystery functions that affect the sound but that I am not qualified to describe. there is also a gate sequencer, so you can basically set two different lengths of tones to trigger as you desire. The sequencer is weird and rudimentary, but functions perfectly."
