I've got the mpk25 hooked up to reason 5...when i load up an instrument it plays like normal....but when i try to add more instruments to the track i get no sound from it. But it shows that it is recieved something. can u please help me?

I had exactly the same problem. You need to press the "Track Push" knob when you have selected the track you want you can then hit "play" to play the track.

Make sure you do NOT send the notes back to the MPK25, that is echo is off. If you echo them the data will be confused. This will be a setup in the Reason SW.

I'm not familiar with Reason 5, but many midi track recorders need each instrument assigned to different midi chanels to be heard back. Check the manual in how to assign the midi tracks. Also, the playback has to be through a unit that is multi timbrel capable. Good luck!

I'd say the click track starts from exactly when you hit play even if you've hit play not right on the beat. There might be a setting or preference that can fix this.

Try rewinding back to be right on the beat and see if it syncs with the click

yea im having the same issue.reason worked fine on my other comp.but as soon as i installed it on my laptop, i got this problem,it only plays the first instrument i load on my audio rack.if you toggle to the rear of the audio rack (press tab to view) the wires are not connected correctly.so i added a line mixer 6:2 and re routed the wires myself..and got it all working.

check the instrument's "show programmer" tab at the bottom of every patch you plug in. if its on every single sound fx that you use, then it's something else, but for the most part, here is where your staccato comes in to play. tweak the OSC 1 2 etc, then the "portamento".

i hope this helps, i kno how ugly reason makes there products to not work for the user's advantage.

okaye, i justt figured itt outt, hopefully you gett an email aboutt this postt...

so anywayz yo,

how many instruments you have hooked up to your mixer? thats the key, #1.

make sure you have atleast ATLEAST 2 mixers in your start up program, once you use the max output input for your original mixer, the next instrument patch you load will not be routed, (no more space), you'll have to route it manually (press Tab) *get familar with routing your own devices, for reverb/chorus and such,

this applies to everything about recieving sound from your project/keyboard. and just route your extra devices on the new mixer --they go up to 14 channels, i have like 22!
so thats my solution, hope itt applies.

Add the new inout to a different track, then merge the old plus the added track.

It sounds like you may be confused on what the MIDI part actually does. MIDI records your performance, not your sound. Then you assign and play back the recorded performance to either a virtual instrument (in which case you should here sound from your computer) or to a real physical MIDI capable instrument (in which case you would here the sound coming from that real instrument instead of the computer).
The ends of the MIDI cables themselves are identical, not IN or OUT.
