Now that my SSP has returned from the dead…I have a question.
You mention in your Wiki (Latency · TheTechnobear/SSP Wiki · GitHub) the following interesting tidbits (emphasis mine):
“ok, now truth is the above was a bit overly complicated …we could also use. PLTS → OUT : 3/4 INP 1/2 → OUT 1/2 now connected QPAS to inputs 1/2…the reason I used 5/6 in first example is beginners often incorrectly assume there is some kind of magic connection between inputs and outputs … there is NOT , INP 1/2 in no way relates to OUT 1/2.”
“something else we have not discussed here is the relationship between the SSP audio interface IO and how they relate to INP and OUT modules and flexibility there. but all I’ll say for now, is the ‘default’ mapping, that maps physical to virtual io ports has a bit of flexibility. and also whilst I used 1/2 above for simplicity… Id often use the higher numbers (above 16) so I dont mix physical IO with virtual IO… unless thats what I actually want”
In using the SSP as an audio interface between my DAW (Logic Pro) and Eurorack, is there a way to use the same channel numbers for input and output? In Logic, you can use the I/O plug-in to create a virtual send/return loop through the SSP. But if I use the same USB channels to send and return on the SSP, I get feedback. I’m currently using alternate channels (i.e., OUT Ch 1 & 2, IN Ch 3 & 4); otherwise, feedback ensues. I like the idea you mention above about using higher numbers (> 16) to avoid mixing physical and virtual I/O. Can you expand a little more on how to configure SSP’s INP and OUT to make that happen and avoid the feedback?
