midi dump for controller patch

October 8, 2007 | 2:24 pm

I was wondering if there is a way to make a something like a midi dump from external gear, for example a beat box and send this data to a maxmsp patch. so if I change the preset in the beat
box I always receive a update of all the controller values of the beat box in the max controller patch without creating a feedback.
every help will be much appreciated.

I think it depends on the external gear.

As an example, I have a PodXT which I use for effects. I’ve made some Max patches that communicate with it via MIDI so I can control it more easily. When I turn a knob on the gear, I can get a knob to turn in Max and vice versa. But when I switch presets on the gear, it doesn’t dump the settings via MIDI so Max gets out of sync. This is a limitation in the hardware because it was not programmed to send its state when the preset changes, and there is no way to do a dump of the current state.

I have software that let’s me save and dump presets to that gear, so it is possible. But it uses a lot of proprietary SYSEX messages, and I think it would be a lot of work reverse engineering that and getting it to work in Max. I didn’t feel it was worth the effort so I ended up doing all my preset management in the Max patch itself.

On the other hand, I have a MIDI controller which has a button to dump the state of the entire device over MIDI, so it is easy in this case because the hardware designer provided the feature I needed.

So really it depends on whether the gear provides a feature to do the dumping, otherwise you’d probably have to do a lot of SYSEX hacking. I’d suggest you use some MIDI monitoring software and watch what messages your gear sends to the computer and see what you can do with it.

Hi Adam, thanks for the reply.,
The idea came from software like sounddiver, but it seems to be a hard way o do that. :(
