Firstly, /dev/sequencer is an OSS device, not native ALSA. "aplaymidi" (from the alsa-utils package, you probably have it installed) can be used as a native ALSA MIDI player, Secondly and most importantly, CMI8330 does not support hardware MIDI. You do likely have a 26-pin "waveblaster" header available on the card, on which you could plug a wavetable MIDI card after which you would have hardware MIDI support but the chip itself doesn't (nor does snd-cmi8330 currently have the required MPU-401 support that would be needed to make that header work but that's probably easily fixed). Nor does snd-cmi8330 supply access to the OPL3 emulation in the CMI8330 chip that I suspect it does have, but don't regret that much; the sound produced by running MIDI through an OPL3 is quite horrible... A MIDI file is just (heavily simplified) a series of "note on, note off" commands and you need something to turn these commands into sound. If you dont have the hardware to do so, you will have to use software. Try a software synthesizer, such as Timidity. I'm not an expert in setting it up, the manual will help...
