Title: Flipping CC values on hat controller
Post by jalnn on Aug 14^th, 2003, 10:39pm

Hello:

I would like to flip the continuous controller values from a hi-hat pedal (CC04) on Roland drum pad kit for use with Gigastudio drum samples. Gigastudio sees the pedal as closed when it is not in use (0), and open when (in fact) the pedal is fully closed (127).

I have installed MidiOx and (in the MIDI Devices dialog box) I have selected the ports for input (MIDI CH10 on port 4 on a USB MIDI inteface) and output (MIDI CH10 on port 6, internal). I see activity, both in and out, in the MIDI Port Activity window.

In the Translation Map I have defined
"When Input Matches":
CH: 10
Event Type: CTL
Ctrl #: Min 4/Max 4 (for foot Controller, CC04)
Amount: Min 0/Max 127

"Set Output To":
CH: 10
Event Type: CTL
Ctrl #: Min 4/Max 4
Amount: Min 127/Max 0

I can see on the Monitor-Output that when I hit the hi-hat controller pedal I generate CC traffic.

In 4 (input on port 4)
Port 6 (output on port 6)
Data1 4 (for Foot Controller)
Data2 127-0 (the CORRECTED CC values, which is great)
Chan 10 (correct)
Event CC:Foot Controller (again correct)

When I ran a test before making mapping changes the values in Data2 were 0-127, so MidiOx is flipping the CC correctly internally and showing them correctly at output. The problem is that Gigastudio DOESN'T see this flip! The CC messages it is receiving are the same, and so is the behavior of the hi-hat.

Any help you may be able to provide would be very welcome.
Thanks in advance.

Check carefully that GS is reading the right port... It sounds like it's reading the unmodified CC values rather than the modified ones.

Can you please be more specific?

Peter's right: you need to output on a virtual or hardware port that Gigastudio will listen to. To do this with a hardware port make a loopback: run a MIDI cable from port 6 (output) to another input port that Giga is listening to.

You could also use a Virtual MIDI port. We've heard that MIDI Yopke is incompatible with Giga, because of their weird startup port sniffing behavior, but you could try the Maple drivers.
