Numeric Keypad to Send Channel-Bank-Prog Change (for Kurzweil K2700)

Question

MIDI Target Manufacturer(s): Kurzweil Music Systems

Basic need is to have a way to send a random program change with a single keystroke. (Tap)

I envision a 10 key numeric keypad, with CLEAR and ENTER buttons, and a display field. You to type in a patch change number, have the display field show the numbers as typed, then tap the “enter” button to send the patch change. it would basically look like a calculator

Ideally be able to enter a four digit number and have the app parse it into bank followed by program change, to mimic the patch numbering system of my Kurzweil K2700.

it would also be nice to have a mode where you could enter channel, bank, program change which will allow you to send the change to any destination in a complex midi rig. You would enter a decimal or similar as a separator character…

Grok was telling me that this app can do it, kept referring to being able to have a button send a character to a display control and also kept mentioning being able to use scripting but I couldn’t find any mention of that in the manual…

Guidance appreciated, thank you

WOW! Really impressive! Can’t wait to try it… thanks!

If there is some logic to parsing the K2700 four digit numbering, I can add that.  But I did not find it in a quick scan of the K2700 manual.

Also interesting that Grok sort of understood the basic concept of how this was put together.  If I post too many of these solutions I will be out of a hobby as AI takes over.

Yeah, AI has many of us questioning our future relevance.

Kurz uses the obvious scheme of combining Bank Select LSB (CC 32) and Program Change messages to recall patches, so for my current need-

entering 0-127 sends CC32 0 + PC 0-127
entering 128-255 sends CC32 1 + PC 0-127
entering 256-383 sends CC32 2 + PC 0 -127
etc....


An alternate implementation would facilitate entry as "bank.PC", i.e.-

entering 4.100 sends CC32 4 + PC 100

this could be extended to include channel-

entering "3.4.100" sends CC32 4 + PC 100 on channel 3- this could be very useful in a complex live rig.

Although Kurz uses either CC0 or CC32 for Bank Select, for universality the various options need to be considered, different combinations of CC0 and CC32 are used for bank select.

I've been using the hardware MIDI Patch Changer Keypad by Music Technologies Group- it's pretty well thought out- you might check out the documentation for ideas. Having this functionality in an App with WiFi MIDI would be super convenient.

quote from the web page:

Manual mode lets you send Program Change as well as optional Bank Select MSB and LSB.
 
Preset mode sends program-change-per-MIDI-channel as well as Bank Select on all 16 channels simultaneously -- per preset.
Send 180 bytes of MIDI data of your choice ...controller data, system exclusive, RPN, NRPN or anything! ... per Preset. (v3.00+)
Holds 200 Presets. (v3.00+)
 
Chain mode let you build a song list or Preset list for even faster performance live.
Holds 99 chains of up to 18 Presets each. (v3.00+)
 
Speed Dial hot-key combinations all access to your 9 favourite Presets. (v3.00+)

The most important feature of this is to not send anything until the Enter is pressed; while playing, you can quickly type in your patch#, it sits there until you need the patch, then one keystroke calls it up. Might be great to have the Enter button be as large a target as is possible.

This is so great that you've done this... let me know where I can make a $$ contribution to your continuing attention.

Got an improved version posted now.  It does include the Bank LSB / Program Change split.  Nothing happens until you press the execute button, which you can make as large as needed.

We have built a setlist manager in MD.  I may need to go back an see if it can be freshened up.  Adding the keypad for direct access is an obvious upgrade.  https://mididesigner.com/qa/10216/flexible-setlist-manager?show=10216#q10216
