debug patches?

[Mark Harris]

hi, 

is there anyway for the axoloti board to send back debug text to the connected client when live?

specifically, when Im running sub patches with multiple voices, sometimes Id like to get information back about whats going on with a particular voice...

I cannot easily send it back via an outlet, as all voices would drive that outlet.

the only thing I can think of doing so far, is to use polyindex to drive a switch to output the data to N outlets... 

but this would possibly get cumbersome if trying to debug a few different variables...

thoughts?

note: this is really occurred as i was doing poly multi stuff, and so different voices behave differently, I recognise usually, you can just debug one voice directly with dials/scopes.

I think a debug 'statement' would also be useful when developing new .axo objects.  

(I think the arduino has this kind of debug function, as Ive seen it on linnstrument videos)

Hi Mark,

You can print a text message from within an object to the log window with

TransmitTextMessage("hello world");

for printing variable you can use:
TransmitTextMessageHeader();
chprintf((BaseSequentialStream *)&SDU1, ...);

chSequentialStreamPut((BaseSequentialStream *)&SDU1, 0);

where ... are printf-style arguments

Printing continuously at dsp-rate will cause underruns, since once the stream buffer is full it will block execution until there is space again. So only print "significant events", don't try to dump data at block rate.

Live interacting with parameters and readback to dials/scopes of (polyphonics) sub-patches is still a complex issue to deal with...

Using patch/polyindex to selectively output data from within one voice to one outlet should work.
