I'm in a world of confusion trying to figure out the best way to chain and control a bunch of devices which I've previously had working "OK but not perfectly" with just the M4+. Now that I've added the A4+, I can't seem to figure out a workable method for chaining the two devices, particularly with regard to getting USB audio from an iPad connected to M4+ to an iPad connected to the A4+.
I'm also getting a lot of static-like clicks and pops which I'm guessing are lost buffers or incorrect master/slave clock relationships. This occurs even when only having an iPad connected (no other devices) to one of the device ports on A4+. Changing various clock/buffer settings doesnt seem to help.
The A4+ and M4+ both have latest firmware.
Until the arrival of the A4+, I've used the M4+ alone, resorting to using the analogue output jacks on some of the devices. It was messy due to iPad jack foibles, but workable.
I hoped the addition of the A4+ would release me from those restrictions/workarounds and I'm now hoping my brain is the problem - I'm finding it very difficult to figure out how to route USB audio from M4+ to A4+.
One problem is the missing iOS app for A4+, which means I have to give one of the device ports up to the PC I'm using to access and configure the A4+. When can we expect the iOS iConfig to support A4+? Months or weeks?
OK - some details:
I'm in a trio which uses multiple MIDI devices and loop stations. My setup is pretty much self-contained - the only "connection" between my system and the other band members is I supply global MIDI Clock to the band via an RC505, which routes to a DIN repeater which delivers the clock to the other members and back to me via DIN. I need that clock signal to propagate into the A4+ and the M4+, which should then propagate to my two iPads and a VoiceLive Touch2 which I use for vocals and vocal looping.
My MIDI controllers comprise an FCB1010 and a Roland GI-20 (I use a Godin Multiac guitar).
I use two iPads. One runs software instruments/samplers, the other runs Loopy HD.
IOW, one iPad (iPad A) makes sound, the other (iPad
captures those sounds and loops them. Additionally, I feed analogue guitar and bass from our X32 mixer into iPad B for looping in Loopy. I monitor all iPad B inputs via Loopy, which should feed the A4+ analogue out. So iPad A only needs to route USB audio to iPad B.
RC505 - delivers MIDI Clock to all devices via DIN repeater.
VoiceLive Touch 2 - needs to receive MIDI Clock (from either iConnect device) and CC control from FCB1010.
iPad A - Currently connected to device port 1 on M4+. Needs to receive Control input from GP-20, routing audio to iPad B via USB.
iPad B - Currently connected to device port 1 on A4+. Needs to receive MIDI Clock, Control input from FCB1010, routing audio to A4+ analogue out.
Windows 8.1 Tablet - runs iConfig, connected to device port 3 on M4+ and (via second USB cable) is also connected to device port 2 on A4+. So that is the way I've chained the USB audio from A4+ to M4+. Is that supposed to work?
I could run software instruments and samplers on the Windows 8.1 tablet in lieu of iPad A, but I prefer iPad A for multiple reasons.
NOTE: I'm getting a LOT of crashes of iConfig on the tablet, nearly always involving msvcr120.dll.
As some others have noted, the A4+ seems to freeze sometimes.
Any suggestions appreciated!
