Hi - I just received the Mixer and VCA/F today, I'm not too happy about the panning by CV. I tried modulating with EMW LFO (tri or square) and with a different 5V modulation source through QMI, both resulted in abrupt "clicks" as the panning sets it, even with a slow/soft triangle, that pretty much makes CV panning useless to me, and with zero documentation on the CV input (none in the box, and link to "manual" on website just reloads the page here..), I'm not sure if the issue is with voltage or the unit itself. After disconnecting the CV panning cable, there is several seconds of noise going into the mix, almost like there is some "stored up" voltage (capacitor?) that is released slowly...very nasty (not in a good way). Except for this the mixer seems fine.
My direct out is also mounted upside down, confusing, but I'm not using this feature anyhow.
Regarding the 4x VCA/F, pretty happy with this one!
Aw man, that does not sound good - I have a mixer on its way to me.
I believe the panning CV should be +ve voltage only, like with Buchla.
If I'm lucky, I might get mine tonight - if so, I'll report back.
Wow, this post got me in a panic too - so I rushed upstairs to test it out (got someone coming round to possibly buy one later!)
Have tried all inputs with sine waves going directly into them, and have noticed virtually nothing in the way of clipping. Maybe a VERY subtle "rounding-off" when run at full tilt, but nothing to worry about.
Bear in mind I have only been testing the inputs one at a time so far, rather than a mix - so maybe you have to be a bit more careful when combining multiple inputs, in order to not clip the output bus (this is the same with all mixers)
I then tried the panning, and am pleased to report that - certainly on mine - there is zero clicking when used to pan back and forth. And that's on a LOW sine wave, so you'd hear it if there was.
Have been using an output from Maths, with the output attenuated down to nearer 5v. Works exactly as expected.
Obviously you WILL hear clicks and pops if you use a saw/ square or similar "edged" modulation source - and sometimes digital mod sources can have unwanted artifacts which can cause these kind of things. I also had various LFOS that were no good for this kind of job, and added little clicks/ pops at their peaks, as the sines/ triangles were essentially shaped saw waves which had every so tiny glitches in the waveforms, which can cause clicks/pops when used to modulate VCAs 9and sometimes filters too)
Hope this helps
