MIDI Apps - who want some ?

Other Hardware Audio

Hey guys, while we wait for some final parts on our Drum Machine project, I was wondering on some small MIDI Apps which would take just Midi Input, Output and some sort of Interface to see what's going on and make choices.

Here's a few ideas:

  1. Arpegiator - simple or complex
  2. Mellody - you play a chord at the bottom of your keyboard, and at the top, the white keys follow the mellody of that chord.
  3. Key Switching - lets you select your midi channel by using the lower keys of your keyboard. Most MIDI controllers have a channel selector but are a bit tricky to use. With this, you can select things faster
  4. Key Transposer - the lower keys let you transpose the whole keyboard with one touch

And so on...

What you guys think?

Best Regards, WilliamK

Another idea I just had. :wink:

  1. MIDI Loop Recorder - for when inspiration strikes. :wink: You record something, let it loop, play along, record something else, and so on....

And yet another idea:

  1. MIDI Playback for Live usage. You record some midi tracks, save into the flash or memory, and have it play tracks with the midi keyboard. EG: Note 60 starts a bass line. Note 62 a Synth Line 1. Note 64 Stops Synth Line 1 and Starts Synth Line 2. And so on.

I like the usage of lower keys as trigger - Some thinking-out-loud ideas...

  1. Start Stop a metronome and adjust its speed (follow the rythm)

  2. Switch on/off/dim my LED lights above the sheet music.

  3. Send a signal to my PC to switch to the next page of sheet music e.g. page-forward in a PDF; another key to start at the first page again. A far more complex application could include selection of PDF's etc. No need for PC keyboard/mouse, Midi driven application

  4. Make a PC MP3 player MIDI controllable, for play along with some music - practice .. some similarity with 9,

  5. Start my coffee machine !

Hehe, good ideas indeed. :wink:

I am working on something that converts a 3-axis accelerometer into midi control data (changing in real time volume, pitch bend, expression, vibrato, special SysEx messages etc.)

:wink:

william,
I would kill for an arpeggiator. In fact, i was searching for one when I found your drum machine! I would pay for the code like you do with the drum machine (which I will do as soon as I finish my current project).

I also like the idea of a midi loop recorder

@antman - I made an arduino based arp based on the RPG8 in propellerheads reason - GitHub - hotchk155/Arduinopeggiator: **** THIS REPO IS NOT THE LATEST ARP PROJECT. PLEASE SEE https://github.com/hotchk155/arpie INSTEAD ***

(clip shows it not quite finished :o)

The main Midi functions I've always wanted from such a box: modulation on Midi messages.

  1. Midi Delay: A Midi based delay effect like the ones proposed on Synthedit based VST modules.
    When transmitting a note, repeating it 2*3 times more at a configurable delay, but with velocity reduced. A Midi emulated version of the Delay effect indeed.

  2. Route and replace - e.g. : replace Modulation by current note Velocity
    That would allow for example to command the cutoff filter of the synth engine with velocity.

  3. Midi LFO / A(D)SR applied on Modulation or pitch bend.
    With some clever math applied to the incoming Mod / Pitch Bend CC messages, add an LFO or state triggered A(D)SR to the modulation parameters, or any other one for sound enhancing purpose.

That's all I have on top of my head, hope it helps.
