Setup problem

Hi,

right now I can not get out anything useful out of imitone. There is s microphone going into my audio interface and fro there it is routed to another interface over adat and there are the monitors connected. What I get is a clean sound from the mic on my monitors.

I choose ASIO in imitone and the channel the mic is connected to. I see something coming in but only randomly some notes are generated. Just junk nothing real useful.

If I switch in the monitor headphone icon in imiton I hear some heavy distorted sound out of the speaker connected to the laptop. How is this coming onto this speaker anyhow? ASIO signal routed to the multimeda driver? There is no out setting in imiton so I wonder, how it is processed and end up on that speaker.

So what I can definitely say right now, signal path to my monitors are fine. I can play music, I can use the mic and nice, normal sound. Some sound source connected to imiton, heavy distortion on the laptop speaker. ASIO path is not affected. Still nice signals on the monitors.

Any idea how I can get something useful out of the program?

Thanks

Thomas

Re: Setup problem

I did some  more investigation. I connected a goMic USB to the laptop and now it is doing what it is supposed to do. Generate midi notes. So this seems to be a ASIO issue.

I am using the kernle driver to access the goMIC. imitone is telling something about 9.x ms latency. But what I hear is far more.

Did someone do any testing with ASIO so far?

Thanks

Re: Setup problem

Hey, Thomas --

The monitor function outputs to the "default" speaker for now; I'm tentatively planning to make that configurable later.  What you hear from the monitor is the audio coming into imitone's microphone input, after some downsampling.  I'm not sure what's going on with your mic input -- is there more than one program using that interface?  I've had trouble with sharing ASIO drivers between imitone and my DAW before.

USB mikes tend to be a great workaround for device sharing issues on Windows -- particularly because imitone doesn't need high-quality audio.  The latency estimate you see is very rough and based on buffer-size; it tends to be inaccurate because of hidden factors in the OS.  (For instance, the values it shows for Multimedia Mode are totally bogus.)  Try ASIO4ALL with that USB mic for better latency.

I've done quite a bit of testing with ASIO4ALL, and a little with an PreSonus FireBox ASIO driver.  I've had issues with audio from the FireBox corrupting badly when CPU usage on its stream exceeded ~60%, and corrupting tolerably when using the FireBox from imitone and Ableton at the same time.

Let me know if any of this helps.
