Thinking about it further, this is so good it warrants being turned into a stand alone app that can be run on a much more basic hardware setup for people who can't/don't want to build a full blowen MBSEQ.

TK, you have out done yourself here. Up until about 15 min ago I though nothing could top the MPC for this type of thing and you've beat it! Well done. The Beatstep sends the polyphonic aftertouch data well and is working correctly at controlling the note velocity.

Great. I'll try this out once the kids are in bed tonight and I've got a bit of peace and quite. I have also got a Arturia Beatstep to check that it transmits polyphonic aftertouch. Does the X-Key work correctly?

I had one of these cables delivered today and it works. http://pages.ebay.com/link/?nav=item.view&alt=web&id=300340091375

The copy function would be very useful. Being able to use the Eucliden generator could provide some really interesting repeat patterns. Maybe pressing the copy button in the edit window copy's the selected track then in the repeat config you press paste and the contents of the clipboard are pasted into the selected pattern? If the copied track is longer than the destination pattern the extra data is discarded. i.e. A 32 note track is copied into a 16 note pattern notes 1-16 fill the pattern and notes 17-32 are ignored.

That sounds like a far more flexible approach to pattern generation.

This sounds great. I think 16 steps would be enough. You mentioned in a previous post that note offset could be introduced, this would also be useful. Maybe it could work like the rotation parameter in the Euclidean generator?

I've rolled the firmware back to 4.087 and the problem persists so I guess it must be a hardware problem. Now I need to decide if I can live with the problem or remove the LED matrix and risk destroying the unit.

It's working correctly now after a bit of messing with the router/bus settings. I can already see this is going to be a great feature. I like the 1/6th and 1/24tn settings, they provide some new options that no existing (the I'm aware of) can do. It makes me think that it would be great to be able to chose a Euclidean as the repeat rate. All in all its really good, thank you for taking the time to do this.

Doh! It's working now. It seems that the first repeat triggers immediately. Is this happening for you?

That was quick! I have loaded the firmware but I can't "activate" the repeat function. I have configured a track as a drum track and enable repeat on all the instruments. Im using a Akai LPD8 running into Ableton live the being sent to the SEQ via USB and then back to Ableton to trigger an instrument. The MIDI routing is fine as I can trigger the instrument with the controller, I just can't get any repeats to happen. Am I missing something?

It seems that the Arturia Beatstep transmits polyphonic aftertouch in response to pad pressure, has a hardware midi output, A CV/Gate interface and 16 encoders thrown in all of less that €100. It looks like it will be the ideal add on pad controller. I'm borrow one this week from work to confirm it does transmit polyphonic aftertouch and report back.

Thanks for the suggestions. A & B: I'm pretty sure the the anode/cathode are correct as all the other LEDs in the matrix work correctly. C: I'm using MBSEQ 4.088 that I compiled myself, I might roll back to the offical 4.087 release and see if that makes a difference.

Yes, that is what I had in mind, the Seq CS isn't really suited to triggering the notes. A big part of the vibe of the MPC is the pads, I think something like a korg nano pad or akai LPD8 connected via USB OTG would be ideal, unfortunataly neither of these devices transmit polyphonic aftertouch. As long as there is the option to assign the repeat function to a CS button and the behaviour of this button can be set to latching and momentary. Maybe press and hold the button it behaves in a momentary way and two quick sussesive presses it latches on, press again once and it latches off. Also the option to have an LED assigned to the button, I think I would personally use the "Fast" button and LED because I haven't found myself using it yet.

I've just built a TPD for my MBSEQ and have a problem with one of the Red LED columns. The first colum of Red LEDs on the the righthand LED matrix are always on, apart from the bottom one. Strangle, when I power on the device and the text scrolls across the matrix the problem isn't there. I'm guess the problem is caused by a short/open connection somewhere but I really don't want to remove he LED matrix unless I have to. Has anyone got a idea as to where the fault could be?

Very Cool... I'm tempted to buy one.

I've been think about this further and how the famous Akai Note Repeat could be improved based on my own experience. One idea I have come up with that would open a new world of possibles would be to be able to select repeat interval on a midi note level i.e C-3: 1/8 Note Repeat C-3#: 1/16 Note Repeat D-3: 1/4 Note Repeat ... etc This would be amazing for drums and absolutely killer when the output is triggering arpeggios. Being able to adjust gate length as a percentage or interval per note would also be good.

I'm curious if there is an Akai MPC style Note Repeat function in the MB SEQ firmware. I've had a look about and there doesn't seem to be an option mimics this. If you aren't familiar with Note Repeat it's a very simple but powerful feature. It works like this, you hold down the note repeat button and a window opens that allows you to select the note interval (1/16 Note, 1/8Note etc) and swing percentage (57% is the magic number). You then hold down a pad and notes are triggered at the selected interval on the beat, ie. If you don't hit the pad on the beat it doesn't start triggering notes until the defined note interval is reached. The pads also transmit polyphonic aftertouch which controls the velocity of the notes being triggered thereby making it very easy to creat expressive patterns quickly and in real time. The Sonic Potions LXR implements a similar feature in its performance mode that works really well.

The board I'm using has a 5V > 3.3V circuit so I'm safe there. The point you make about the voltage drop on the diode is valid and could explain why I'm having no dice with the 3.3V supply from J16.

Here it is!

Are you using RC2 for the select line of the ethernet module?

The SD Card uses RC1 as SS and the Ethernet module uses RC2 as SS. I have both working at the same time configured this way, no changes to the code are necessary. One thing I did find that the Ethernet module wouldn't work running off the 3.3v suppy from J16. I had to jump 5V from the discovery board to get it to work.

My case arrived today! I'm as excited as a kid at Christmas, as my MBSEQ will be completely finished before the weekend is out! Thanks Kristal=
