Thanks for the tip!

I'm trying out LMMS and Cakewalk and I'm in over my head, can't find anything about MIDI filtering. I'm sure there's a huge learning curve to DAWs. Can you recommend a good simple, inexpensive DAW without all the bells and whistles?

I'm only getting midi input options for my physical midi controllers and something called "Vienna Instruments MIDI." How can I get synchron piano to accept midi-in from something like midi-yoke or another virtual midi port? How can I get it to receive other inputs than just my physical controller?
 
REASON 1: When playing live, I need to filter out the "all notes off" message from my older digital piano, in order for the sustain to work correctly.
 
REASON 2: I would also like to record a live performance to a midi sequence, save it to my computer, and play it back multiple times through the bosendorfer, recording one mic setting at a time for more accurate mixing after the fact.

So the B0/B3 issue was only the channel number apparently. I switched the LPK25 to channel 1, and it's STATUS parameter became B0. The sustain still works on this controller, and not on the Technics piano.

Using the mouse to press the Sus button on the user interface, then playing a key on each keyboard yielded the same results, which made me realize it wasn't a problem with the sustain pedal on the Technics, but perhaps something with the note on/off messages.

Turns out the Technics is sending a second note on with velocity 0, followed by an "all notes off" message on key release.

I could theoretically filter out the "all notes off" message using midi-ox or something similar, but there doesn't seem to be any options in the synchron player for taking input from anything other than directly from the controller itself. Which begs the next question. How can I record from a sequence?

I finally got this thing set up today, and I'm having a little trouble with the sustain pedal. It dies really quickly, kinda holds out the reverb a little, but it's not the same nice long sustain as when I hold a key down indefinitely.

I just tried it with a different controller, and it seems to work on the small controller. I used Midi-Ox to get a readout of the two controllers and here's what I found:

The 88 Key Technics SX-PR250 on which I was having the issue gives me this readout for pressing and releasing the pedal:

TIMESTAMP IN PORT  STATUS DATA1 DATA2 CHN NOTE EVENT

00000E6A  10  --     B0    40    7F    1  ---  CC: Pedal (Sustain)

00000C32  10  --     B0    40    00    1  ---  CC: Pedal (Sustain)

 

The Akai LPK25 which isn't suitable for playing piano, but the sustain test worked properly, gave me this readout:

TIMESTAMP IN PORT  STATUS DATA1 DATA2 CHN NOTE EVENT

00001030   9  --     B3    40    7F    4  ---  CC: Pedal (Sustain)

00001328   9  --     B3    40    00    4  ---  CC: Pedal (Sustain)

 

The only real difference seems to be the B3 rather than B1 in the "Status" column. I'm continuing to research what this means, and if all else fails I suppose I can have midi-ox filter that parameter, though I'd rather not have to go through midi-ox just to play this thing properly.

I'm impressed by the demos I've seen of the Bosendorfer Imperial, and doing some research before purchasing. I have some questions about the process of downloading and installing.

Since this is delivered as a download, not a hard copy, will I be able to back it up on an external drive in case I need to install on a new computer at some future date?

I've seen companies go out of business or change their licensing retroactively, and then not been able to access software that I had purchased. I want to make sure that I will be able to restore my purchased software from my own hard copy at a later date, should the worst happen.
