I have version 1 without the clock ports. I’ve connected the Clockworks to the Sequencer Drum through the Trig In port. Triggering the first step can be as slow as the Clockworks, but the remaining 7 steps are still determined by the rate slide of the Sequencer Drum. So you have to manually synchronize the Clockworks tempo with the Sequencer Drum rate. That doesn’t bother me so much. It’s just that I’m stuck with a limited range of tempos to play with because the Sequencer Drum rate doesn’t get slow enough. The upper 3/4 of the rate slide range is way too fast to be very useful.

I wish Julia Truchess was reading here to offer some insight

The mono EchFlanger probably first appeared around 1977 or 1978. I’m pretty sure I have seen it in a 1978 catalog.

I believe that the Stereo Polychorus with the wooden box was introduced in the late 90s.

The wooden box period seems to be from the late 90s to about 2005.

I’ve wondered if the new Analogizer is in any way a descendent of the Ambitron.

I’ve never understood how tap-tempo tremolo is more useful than a tremelo that can sync to other devices like click trax, drum machines, loopers, etc.
