Ultra simple Sequencer App For Whammy WH4

[Jaicen]

I'm wondering if there's anybody here that can help me.

I'm looking to build a controller pedal for my Whammy WH4. I want a box that will allow me to sequence MIDI values between 0-127 on channel CC11, and possibly a bank select switch on CC0.

My thinking is that I could use 16 sliders to control the notes in the sequence, and control the tempo or whatever through an encoder and LCD. Perhaps the LCD could be used to bring up presets?

So, does this sound like something that could be viable?

You just described the original MB64seq hehehehe

Edit: That's a yes. Just use a timer (or the clockbox like the rest of us eh) to send the notes which you can store in an array, and then use ain_notifychange to change the contents in the array.

With MBSEQ V2 (vintage option for analog controllers) you can do this

Ermm, ok great, I think.

Actually no, you've lost me! How do I do it?

EDIT: Sorry, I don't want to look like an idiot here, but I have absolutely no skills when it comes to programming. By using ain_notifychange, does that mean I use a pot to scroll through values in a lookup table? If so, my thinking is that the notes can be entered onto an LCD screen, and only one encoder and a few buttons would be needed. Maybe have say 16-LED's to show which step it's on.

As I say, this isn't something i'd be able to code myself, I know that for sure since I don't have time to learn enough to get me to this standard (I already work two jobs), but if somebody was willing to do the code, i'd certainly do all the hardware stuff. I know at least three of my friends would jump at the chance to have one of these on their pedal board.

It's explained here: http://www.ucapps.de/midibox_seq_v2.html

Keyword: "vintage"

Note that MBSEQ V3 doesn't support pots/faders anymore, therefore the reference to MBSEQ V2

Ok, looks like that could work for sure, but it's a bit unwieldy for the specialised purpose I had in mind.

It literally only needs to be able to sequence for CC11, so no note info is needed at all.

Well, it's a lot easier to use a pre-made app and maybe cut down the CS a bit, than to go programming your own seq. Trust me, there's more to it than you think ;)

[Jaicen]

Of that, I have no doubt at all! But as I said, I don't have the tech skills to know which bits are needed and which are not, so I guess it's a non starter. I don't think that this app would benefit from having the two long LCD's and 16 knobs. It would be just as easily programmed using a 2x20 LCD, encoder and some buttons. Think MBSID step A. In which case, MBSeq is massively overcomplex.

Maybe over the weekend you can meet me in the chatroom and we can make a really basic seq :)

[Jaicen]

Stryd, thou art a LEGEND!

Where are you located? Think there may be a time differential to contend with, but i'm up for it for sure.

.au , Zulu +10

But I keep strange hours on the weekend ;)

[Jaicen]

That's cool then. I'll be available friday night, which i'd assume is your early morning, and Saturday afternoon too, so it's all good!

I'm there now mate, jump in :)
