Hi all,
I'm just getting started trying to use Csound with a Doepfer Dark Link. This is a hardware that takes MIDI input and converts it into CV output. Has anyone else tried this yet? I'm on Linux Mint with alsa, and the Dark Link shows up as "hw:2,0,0' using "amidi -l". I tried running midion2.csd (Csound manual example) with the command line csound -+rtmidi=alsa -Q hw:2,0,0 -o /dev/null midion2.csd (not setting -M because I'm not using MIDI inputs, only output) and at the end of the brief run I get ALSA lib rawmidi_hw.c:133:(snd_rawmidi_hw_drain) SNDRV_RAWMIDI_IOCTL_DRAIN failed: Input/output error Is this because I'm not using an input device? I also don't see any output from the Dark Link (monitoring with a multimeter). - Dave P.S.

Have you tried using any other applications other than Csound to send MIDI via ALSA? Something like PD, Qtractor, Rosegarden, etc... On Sun, Apr 19, 2015 at 3:28 PM, Dave Seidel <dave.seidel@gmail.com> wrote:

No, but that's a good idea. Might have nothing to do with Csound. Thanks for the suggestion. On Mon, Apr 20, 2015 at 11:40 AM, Paul Batchelor <ralphbluecoat@gmail.com> wrote:
