Weird multi-channel issue when modifying m_num_ins and m_num_outs as in a multichannel chugin

[nshaheed]

This is a weird one that I don't fully understand. Mostly just writing this down so I don't forget.

I was messing with dynamically setting the input and output channels for my Rave chugin. Basically, when the chugin loads the model file it sets the number of input and output channels based off of whether it's doing forward/encode/decode.

This looks something like this in the cpp:

Chuck_UGen* m_self; // the chuck ugen pointer I'm storing in my Rave helper class

m_self->m_num_ins = m_in_dim;
m_self->m_num_outs = m_out_dim;
m_self->m_multi_chan_size = m_in_dim > m_out_dim ? m_in_dim: m_out_dim;

However if I do that, then run the following code:

adc => Rave r => dac;
r.model(me.dir() + "rave_chafe_data_rt.ts");

1::eon => now;

not only can you hear the output of rave, but the adc is just getting passed through to the dac directly (setting the gain of Rave to 0 doesn't change this at all so it's just stepping over it somehow)
