External Input/Output problem

G'day,

I've written an ASIO device driver which I want to use as input for a SynthMaker executable.

For output I'd like to use a different driver (preferable a different ASIO device, but the standard Windows DirectSound will do fine).

My problem with the output:

- when I select a different ASIO driver, the selected ASIO driver for the input is changed to the same one - when I selected a DirectSound driver, my ASIO driver on the input gets de-selected (and vice versa).

That completely stops my development.

Thanks for your time and understanding.

Hi Tom,

ASIO can only be used for one device at a time, so this is why when you change output driver SM automatically switches the input to reflect this.

Also because ASIO connects to the hardware at a low level you can't use DirectSound at the same time.

Sorry if this rains on your plans 🙁

You mean when I write a (C++) application which opens 2 different ASIO drivers (for 2 different hardware devices of course) the OS only lets me use one at the same time?

I thought that was the case yes and so that's what happens in SM but if you've managed to get round it in your own application then I must be wrong 🙂

Its possible to write an ASIO driver that uses two sepearte pieces of hardware but the syncing is a little iffy unless the hardware was designed for the job Check ASIO 4 All

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
