In fact, it's a long-awaited option because basically Aureal ARL format is plainly the SF2 2.0 but with its own addressing system." Quoted from http://www.xbitlabs.com/articles/multimedia/display/sq2500.html 1) Why samplerate is missing in soundfont_sample_info_t ? The samples in au30gm.arl have different samplerates. 2) How can I create a stream_t for each voice in snd-au8830-synth and use those vortex_adbdma_**** functions in snd-au8830 modules (using ADB instead of WT) ? 3) Refer to http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg11719.html Is it possible to use adb to play the sample loop using scatter gatter DMA ? ( by adding a flag in stream_t to indicate the sample has a loop ) 4) Can those snd_vortex_synth_alloc(), snd_vortex_synth_free(), snd_vortex_synth_bzero() replaced by kmalloc(), kfree(), ... instead of implementing a Memory blocks Management system with those fuctions in util_mem.c ? ------------------------------------------------------- This SF.Net email is sponsored by: New Crystal Reports XI.
