I dont seem to be > able to get them to work aymore except for a global buffer. in the case of sbawe (and emu10k1 in future) they are controlled by sending MIDI controls 0x5d (chorus depth) and 0x5b (reverb depth), respectively. if you mean that these controls don't influence the sound, then it must be a bug. please let me know. > About this too, is there a way to change the reverb/chorus types > that i know the awe64 supports? the chorus/reverb modes can be controlled via a standard GS sysex (or an ioctl of OSS-emulation). the sysex bytes are f0 41 10 42 12 40 01 38 XX f7 (chorus) f0 41 10 42 12 40 01 30 XX f7 (reverb) where XX is a mode type from 0 to 7. > About the sblive sequencer on ALSA, from what i can deduce, it seems > to be a bug in the code that tries to allocate a free channel.. is > there any work around for this? i've been hunting this bug for a long time but not still figured out the condition when/how it happens.. do you have an example midi which can reproduce this problem clearly? it would really help for debugging. > Also about the insert effects on the sblive, I havent found the way > to map them into midi controllers (my guess is that the sblive uses > a global send buffer for effects and send levels per channel so they > cant be mixed that easily?) sorry, the mapping to midi control is not implmented yet. (and iirc there is no good working dsp codes (for alsa) yet.) perhaps we need to extend fx8010 control struct in emufx.c, too. well, for better understanding, let me explain a bit detail of emu10k1 hardware: emu10k1 has 4 individual outputs per channel. two are used for dry sounds, so we have another two mono outputs, which are usually assigned for for chorus and reverb. the above chorus/reverb depth controls the amount of wet tones to be sent to these two effect outputs. an effect will be inserted between an effect output and the master mixer. this can be any effect, not only for chorus and reverb, but also e.g. 4-point surrounds. the effect simply reads the value, which is the sum of outputs from all channels, processes it and outputs to the specified effect route, eventually to the master. ciao, Takashi ___ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel

[Alsa-devel] Help needed with sequencer driver for Mikmod
Nobody answered my previous mail so maybe a better subject will help... I have written a ALSA sequencer driver for Mikmod. The problem is that I can't get any sound from it. It uses simple instruments so it should work with GUS and Trident 4dwave cards. I had a semi working driver before the sequencer API changes but I misplaced it. This current driver is based on alsamod and the drv_ultra driver from Mikmod. I'd appreciate if someone who knows the sequencer could take look at the code. I have a patch against libmikmod-3.1.9 at "http://www.saunalahti.fi/~syrjala/alsa/"; -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ___ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
[Alsa-devel] Problems Playing CDs with the SB Live. Using "kscd"
Hello I have trouble with playing CDs with the SB Live. The alsamixer "CD" volume control adjusts the volume and the sound comes out the the headphone socket. I want the sound to come out of the SPDIF socket. If I play a .WAV file, the sound comes out the the SPDIF socket if I toggle "IEC958 Optical Raw" so "MM" appears. No matter what I try, CD audio only ever comes out of the headphone socket. Another point: - I can be playing a DVD is AC3 passthru mode which disables all the alsamixer controls, meaning that .WAV files will not play while AC3 passthru is playing. Even in this mode, the CD still plays via the headphone socket. Cheers James ___ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel

( rawmidi_hw.c:221: snd_rawmidi_hw_open: Assertion `!(mode & ~(0x0001|0x0002))' failed.) Two: using SND_RAWMIDI_APPEND on snd_rawmidi_open causes an assert then a segfault.. A '0' for flags is fine... (see Three) rawmidi.c:963: snd_rawmidi_write: Assertion `rawmidi' failed. (this error is printed thousands of times... before a segfault) Three: after a while, about a minute or so of playing a midi, the midi starts getting slower and slower.. and CPU usage goes to 0... I'm sure Its not the midi player, as I've tried it's 'DIGIMID' driver (which uses a converted soundfont to play through the digital pcm interface) and it doens't have this problem. (now I've got to reboot... because I can't think of another way to turn off the midi notes that were left on... :) -- Thomas Fjellstrom [EMAIL PROTECTED] http://strangesoft.net ___ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
