Subject:Using ACID with Electrix Repeater - MIDI filter

Hey THERE Peter and SonicPCH,

I encountered MIDI communication problems between ACID PRO 3.0 and Electrix Repeater. I posted back and forth with Peter about this a couple months back... Basically, ACID sends a "seek" when it hits its loop point, which causes Repeater to stop, Repeater doesn't respond to the song position change message that follows and does not start back up.

Here is Peter's last description of the problem:

<<Got it....

This is what the "Seek" does (refering to ACID's MIDI output):
- Sends a MIDI Clock Stop MSG
- Sends a Song Position Pointer to the beginning of the loop
- Sends the continue/start msg

I don't see any work around. This is designed behavior. The goal was to get MIDI sequencers to chase ACID. It sounds like what you need is a mode to not send stop msg or song position pointers.

So I've decided to try this method to solve this problem: My goal is to try to filter out the "MIDI clock stop" message before it leaves the MIDI-OUT of the computer and hits the Electrix Repeater, thus preventing the Repeater from getting the "stop" signal... I've talked with Electrix and they don't have a solution in their hardware...

So, I'd like to try a software MIDI filter on the machine that's running ACID... Have you heard of anyone trying one of these programs successfully with ACID PRO 3.0??? Any recommendations? And do you happen to know the MIDI data that I'd need to filter out to prevent the stop message from leaving the machine?

I'm also planning on attempting to have ACID chase the Repeater (let the Repeater generate the MIDI clock signal...) Does ACID work well in this situation?

thanks kindly,

john

You might like to have a look at MIDI-OX (http://www.midiox.com) which is a splendid piece of software, absolutely invaluable to anyone doing MIDI on a PC. Amongst its multitudinous features are the facility to filter out MIDI messages of all kinds, including the Stop message you are interested in.

The Stop message is actually a single-byte message with a value of FC hex, though you won't need to know that to filter it in MIDI-OX - just select it in the filter dialog box under System Realtime.

MIDI OX will do this for you.

I have had more and more requests for the ability to do what you want. Start a device, but not stop it on a seek or loop point. I will be revisiting this for a future version of ACID.
