Psyscope free is a multi-track synced oscilloscope plugin inspired from Psylab build-in scope.
Features:
_ 4x stereo inputs for multi channels checking.
_ Show individual or overlapped layers , from L, R, or mono sum.
_ Show the summed result.
_ Zoom ‘ n ‘ scroll for precise inspecting, up to sample rez.
_Datas infos: max peak, under mouse db value, ms, beat, sample positions..
_ 3 Skins included that can be customized with state saved to daw per instance.
_ Latency offset setting for daws that don’t report correct PPQ timming.
_Full vector resizable UI.
Available as windows vst 2.4 64 bits .dll. No install, just drop .dll to plugin folder
Note this project is no more updated. A more advanced version called Psyscope Pro, that doesn’t require manual routing, adds multi-track spectrum, provides visualizing of up to 16 signals and many more features n frequent updates can be found clicking here.

_Fixed server corrupting downloads (mid-end june)
V1.0.02 – published may / 24 / 2020 –
_Better anti-aliasing method, reducing a bit « lines spikes » or « holes » effects that could appear at transients/hi freq content.
_Reduced AA computations.
_If double clicking somewhere on the wavform, auto computes needed latency and apply in order to make this position being the start of the buffer loop.
V1.0.01 – published may / 22 / 2020 –
_Latency/offset can be entered in sample or ms.
_Layers/inputs can be enabled/disabled via right clic on corresponding cell.
How to: use multi layers mode - ableton live routing examples

- classic bus routing technique.
1_ Create a new audio track, drop psyscope plugin on it. set « Audio from » to « No Input », set Monitor to « IN », Mute the track.
2_ Create 4 audio tracks (the green ones here), in « Audio from » pick each source track you want, for ex here kick, bass, snare, HH. Set monitor to in, in « Audio To » set to PSYSCOPE, then respectively
for 1,2,3,4 « track in », 3-4, 5-6, 7-8.

2. Sends technique.
1_ Create a new audio track, drop psyscope plugin on it. set « Audio from » to « No Input », set Monitor to « IN », Mute the track.
2_ Create 4 return tracks (A,B,C,D here) with no effects on them, in « Audio To » set to PSYSCOPE, then respectively for A,B,C,D « track in », 3-4, 5-6, 7-8.
3_on Psyscope track, right click on a send « disable all sends ».
4) Now on each track of your live set can send them as want, for ex here kick is sent to A wich will be first layer of psyscope, bass is sent to B wich will be second layer and so on..
