Thanks, slowly getting it...I think.
Probably will get clearer when BiaB Pro arrives (our download speed is not good enough where we live)
I don't need exact cover tracks, more the style and beat.
About 15 years ago I bought a Goldstar midi keyboard which I used with a program called Jammer with an expensive sound card in the PC. I didn't really get to use it much as I was dragged back into another band so my early introduction into midi was short lived.
All that's left is the keyboard (full size) and a Edirol UM 1 whatever which apparently is not compatible with Windows 10. I think the UM 2 may work as I have been trying the original with Garage band without success.
So, happy to think real tracks will play without midi software.
If I buy this coyote software does it link itself to a playback of any midi file or do you have to load it into it......for instance if I purchase a midi backing track from wherever how do I get this midi track to play in the coyote software.
Happy to try midi amd buy the software and even happier if I can get the keyboard to work with it.
At the end of the day I want to convert whatever comes out if BiaB - midi or real tracks to a MP3 file to load into my chord/word program Onsong.
Thanks for you replies, much appreciated.
