" Our Pedz Eurorack module has ground on sleeve, +12V on ring, and wiper on tip. " What happens if someone inadvertently plugs a TS plug in? This description would suggest that +12V would be shorted to 0V. On 10/12/2018 04:05, John Emond wrote: > Our Pedz Eurorack module has ground on sleeve, +12V on ring, and wiper on tip. It doesn't work that well with the Yamaha FC7, audio. It works perfectly with the Roland EX5, linear. It also worked well when tested with a really old Moog passive pedal, again linear. Pedz includes a VCA as well as uni and bipolar attenuators. > > Cheers, > > John > > >> On Dec 9, 2018, at 12:36 PM, Sam Mims <xxx@xxxxxxx.xxx> wrote: >> >> First of all, there are active pedals and passive pedals, and they are all called expression, CV, or other names.

An active pedal will have a phone plug with two connectors (TS, voltage and ground), while a passive pedal will have a 3-conductor (TRS) phone jack - one for incoming voltage, one for voltage back to the synth, and one for ground. >> >> The Ensoniq pedal is passive, and there are definitely two flavors of passive pedals. If I recall correctly, one uses a linear pot, and the other uses an audio-taper pot. I remember once on the road some of our gear got stolen, and I had to use a Yamaha expression pedal with my Ensoniq boards. All the ‘business’ of the pedal happened in just a few degrees of travel of the pedal. So while you will get results using the wrong type of pedal, they won’t be usable in a practical situation. >> >> I have not, though run into a situation where the pedal is wired differently… >> >> Sam Mims >> Syntaur >> >> >> >>> On Dec 9, 2018, at 4:22 AM, Thomas Strathmann <xxxxxx@xxxx.xxx> wrote: >>> >>> On 09.12.18 08:24, Brian Willoughby wrote: >>>> I just ran into a situation where my Ensoniq Expression Pedal is not compatible with a new USB-MIDI controller.
