Starting a Synthesizer with Port Audio and a device input count of greater then two crashes about jsyn HOT 3 OPEN

Upon further reading it looks like the number of inputs is always capped in the DualOscilloscope example.

int numInputChannels = deviceMaxInputs.get(itemIndex); if (numInputChannels > 2) numInputChannels = 2;

Given this, I don't understand how to obtain specific inputs from specific channels?

The example I am thinking of is my soundcard has 14 inputs, but I'm only interested in channels 5 and 6. How is this achieved with this library? Whenever I set the channel indexes to something other then 0, or 1, the library just spits out

java.lang.RuntimeException: Audio Input not configured in start() method. at com.jsyn.engine.SynthesisEngine.getInputBuffer(Unknown Source) at com.jsyn.unitgen.ChannelIn.generate(Unknown Source) at com.jsyn.unitgen.UnitGenerator.pullData(Unknown Source)

Seems like it's not possible?

I need to add some tests or demos for multi-channel input and output.

The JPortaudio libraries on the softsynth.com website are very old and need to be rebuilt with the Mac changes from this:

Generally, the solution is to open 8 channels and then just ignore the lower numbered channels you don't want.

That is just a limitation of the example code. You should be able to use the ChannelIn(5) unit to get the 5th channel and then connect it to a scope.

This seems like a bug in JPortAudio or PortAudio.

@lukasroberts - What is your sound card?
How many individual input channels versus SPDIF channels?
What happens if you only open 8 input channels?
