[Coco] Sound Chaser Multi-Format Music Player BETA

[Bill Pierce]

Actually it is possible Aaron, I have the program set in a wait state while the player is running. The player is actually running in another 64k workspace anyway., but... there will really be no need in the finished program as there will be a complete file selection routine.  You will be able to select from 1-300 songs no matter what format and when you hit play, they will all play in sequence. I've just been too busy trying to get the Lyra portion to play and haven't worked on the selection routine. If you notice, the filename will turn blue after hitting <Enter>, this is to let you know you have that file selected. Then they will turn green after playing, this is so you know that selection has played. There will be a hot key that will bring up a scrollable window with your selections in order of selection so you can go through and delete songs from the selection if you don't want them there. The Play menu will have all the selection edit cmds in it. I guess I need to pause a bit from the players and get the selection scheme finished. 

As far as doing something else while song is playing.. On a Coco, producing sound takes 100% of the CPU. This is why most sound programs have interupts blocked while playing. The midi player on the other hand, has a small amount of time between blocks being sent, but most actions you would do would slow the song down a bit. Try playing an Umuse song, then go to another window and type "Dir". The song will skip or drag while the disk is being accessed and the disk access will stutter slightly. This is because the Midi driver only blocks interupts while it is sending data. When it is waiting on a countdown till time to send the next note, it's in sleep mode. But we are talking fractions of seconds here,

I've been messing around with this today, very nice!  Ultimuse
layback works perfectly over dw4 (the only thing I have to test with,
o real midi interfaces for coco).
Would it be possible to run the player in a separate process so that
he sndchaser interface was still usable?  That would allow the user
o change output devices on the fly from within the program, queue up
he next song maybe, that kind of thing.
well done
Aaron

 Hi Guys,
  I've finally posted a Beta version of the Sound Chaser Multi-Format Music 
layer for OS-9 on my Coco Music site.
 This is by no means a release and is put up for those who would like to try it 
ut and give some feedback. Currently, it will only play
 two music formats. Ultimuse & Musica. Orchestra 90 & Lyra are getting real 
lose to completion and will be added soon as will be a standard midifile 
layer! I have provided a variety of music on the demo disk as well.
 In my Ultimuse player, there is the ability to play Midi through the Coco 
erial port, Speech Systems Midi Pak of which Gleneside's pak is compatable, and 
ny user Midi interface that uses the /MIDI driver. Yep... that means it will 
ow play through Drivewire flawlessly. You can even select which DW sound source 
ou want to use right from the menu. This means all you who've not been able to 
lay Midi due to lack of Midi hardware can now do so with Sound Chaser & 
rivewire.
 The Musica player will play music through the Coco's 6 bit dac or the 
rchestra 90 pak and the Speech Systems Stereo pak, BOTH IN FULL STEREO. Of 
ource you have to have the paks plugged into a stereo sound system for this to 
ork. Now if Aaron would just write in an 8-bit stereo sound driver for 
riveWire that had to write enabled ports... :-)   The Orch90 function also 
orks real well in the emulators.

 What I need:
 I need people with an Orch90 pak and Speech Systems pak to try this out and 
et me know if there's any problems.
 Also, Does anyone own a ColOrchestra Midi pak? or the InterComp Sound Midi 
nterface?
 I have the info on the colorchestra pak and can write a drive in for that, but 
 have no info on the InterComp Sound Midi pak.

 Also... does anyone know how to detect whether or not these paks are present? 
 know there's a way and I would like to be able to disable the menu option for 
hose paks not present on a system on program startup.

 And most of all PLEASE read the SoundChaser.doc file found in the root 
irectory of the Demo disk image.
