In today’s digital-first world, Instagram growth is essential for anyone looking to build a strong online presence. Whether you're a creator, influencer, or business, simply having an account is not enough—you need consistent growth to stay relevant and competitive. Growing on Instagram means expanding your reach, increasing followers and engagement, and strengthening your credibility, all of which play a crucial role in long-term success.

DAW controlling motorized potentiometers

J F — Fri, 13 Feb 2026 12:12:01 +0000

Dear MIDI association and forum members,

Recently, I took a little dive into the world of MIDI by programming a Raspberry Pi Pico (rp2040) to send messages like NoteOn, NoteOff, ControlChange, … to a PC via USB. My DAW (LMMS) is able to receive these messages and play notes or move sliders.

In order to let the DAW change the slider value of a motorised slider, the DAW needs to send messages to the device. Does it do that automaticly or does the device need to send a request? What messages are they? Are they ControlChange-messages or a completely ther format?

Thanks for further advice.

Yours faithfully

Question for the experts. What can you request with MIDI requests?

Gus Shar — Sat, 15 Nov 2025 03:21:18 +0000

Hi Everyone,

I have a question for experienced MIDI users and engineers. I started building an arduino MIDI controller that is currently controlling two connected Keyboards "B" & "C" where I can make changes on the third keyboard "A" such as (transpose and scale change, pitch bend, ribbon and modulations) I did that with great success and many hours of programming and thanks to Chatgpt and KIMI K2 (was amazing).

One of the MIDI ports I have built I want to use as the following:

I want to have an ON/OFF foot switch to where when I press it, the Keyboard A will pass Notes ON/OFF to a fourth sound box "D", and at the same time send a signal back to keyboard "A" to lower the volume for the Upper 1, 2, 3 (Channels 1,2,3) to volume 1.

Also when I remove my foot off the pedal I want to turn off passing the MIDI notes to the fourth sound box "D" but (and here is my problem) I want at the same time to bring back the channels 1,2,3 on keyboard "A" back to the same volume they were in before the initial press down and lowering the volume.

This way I would toggle the sound engines of two devices (keyboard A, and a MIDI sound controller) on the fly with a foot pedal switch. I can easily build the program but my problem is that I don't know how to inform the Arduino of what was the volume of the channels 1,2,3 before they were lowered, so I can have the program fotware to put them back to their initial setting after pulling the foot OFF the pedal. Are there any dump requests that can be done to achieve what I want to do which is to pull the volume value of the channel of the Keyboard A (which is a KORG PA5x)?

By the way KORG did not publish a MIDI implementation chart for the PA5x yet!!

Thanks

MSB and LSB

Al Freeburger — Mon, 27 Oct 2025 15:14:04 +0000

Hi there. I'm trying to understand how MSB and LSB values are combined to produce more precision?

Does the MSB value reflect the full range (say 0-127) with the LSB acting as a decimal or fraction of each of those steps? For example, would MSB 73 and LSB 64 equate to 73.5 in decimal?

Device Name Best Practice?

Peter Hanratty — Tue, 09 Sep 2025 22:49:31 +0000

Greetings,
I recently took my first deep dive into MIDI after acquiring a Roland SC88 Pro and building a custom interface and written software for playing with all 32 channels. I was wondering why the 'MIDI port' meta event is considered obsolete in favour of device name. Assigning tracks to devices based on a numerical index seems the most logical thing to do whereas having specifically named devices implies that the file and the player must agree on what the names are. Is there a standard naming convention for this? If not then what I'll probably do is assign an index to each unique name as it appears in the file. Is that an approach that exists already?

midi events with type ID 0x64, 0x65, 0x06, ...?

Markus Weber — Thu, 06 Mar 2025 22:55:24 +0000

I already parsed MIDI files 10 years ago - or created them.

This is a MIDI file created with MuseScore - I want to parse it, but:

00000000 4d 54 68 64 00 00 00 06 00 01 00 01 01 e0 4d 54 MThd..........MT 00000010 72 6b 00 00 06 d5 00 ff 03 05 50 69 61 6e 6f 00 rk........Piano. 00000020 ff 58 04 04 02 18 08 00 ff 59 02 00 00 00 ff 51 .X.......Y.....Q 00000030 03 07 a1 20 00 b0 79 00 00 64 00 00 65 00 00 06 ... ..y..d..e... 00000040 0c 00 64 7f 00 65 7f 00 c0 00 00 b0 07 64 00 0a ..d.e......d.. 00000050 40 00 5b 00 00 5d 00 00 ff 21 01 00 00 90 24 50 @....!....$P 00000060 00 ff 05 02 43 32 00 ff 05 01 43 83 47 90 24 00 ....C2....C.G.$. 00000070 19 26 50 00 ff 05 02 44 32 00 ff 05 01 44 83 47 .&P....D2....D.G 00000080 90 26 00 19 28 50 00 ff 05 02 45 32 00 ff 05 01 .&..(P....E2.... 00000090 45 83 47 90 28 00 19 29 50 00 ff 05 02 46 32 00 E.G.(..)P....F2.

...

b0 79 00 is a controller event - right?

after a delay of 00 ticks

64

follows, but AFAIK all event type IDs start from 0x80 (to 0xFF).

So what kind of event ID is 0x64? Or what I did not parse properly?

(Later such pattern occurs again)

At my parsing ouput:

...
Delay: 0 ticks
  from 22/0x16 with 1/0x01 bytes: 0x00
'MetaEvent'
  from 23/0x17 with 8/0x08 bytes: 0xff 0x03 0x05 0x50 0x69 0x61 0x6e 0x6f
Delay: 0 ticks
  from 31/0x1f with 1/0x01 bytes: 0x00
'MetaEvent'
  from 32/0x20 with 7/0x07 bytes: 0xff 0x58 0x04 0x04 0x02 0x18 0x08
Delay: 0 ticks
  from 39/0x27 with 1/0x01 bytes: 0x00
'MetaEvent'
  from 40/0x28 with 5/0x05 bytes: 0xff 0x59 0x02 0x00 0x00
Delay: 0 ticks
  from 45/0x2d with 1/0x01 bytes: 0x00
'MetaEvent'
  from 46/0x2e with 6/0x06 bytes: 0xff 0x51 0x03 0x07 0xa1 0x20
Delay: 0 ticks
  from 52/0x34 with 1/0x01 bytes: 0x00
MidiParser.events.ControllerEvent
  from 53/0x35 with 3/0x03 bytes: 0xb0 0x79 0x00
Delay: 0 ticks
  from 56/0x38 with 1/0x01 bytes: 0x00
MidiParser.events.IntermediateImplementationEvent
  from 57/0x39 with 2/0x02 bytes: 0x64 0x00

What event is the the last byte 0x64 (and 0x00) in the last line?

Any documentation, link for its explanation?

Hello! Since this is for beginners maybe it will be published. I made a post in the hardware sub forum about USB-Midi but it is never published.

The post has been marked "Awaiting moderation" for 4 days. I see no way to contact the administrators. What do I do?

MIDI Connection Issues

Unable to connect

Newbie needs help

Bill Fischer — Fri, 27 Sep 2024 01:22:22 +0000

I am trying to set up a connection from a PC to a Yamaha Clavinova using a USB-to-MIDI adapter cable. The hardware connects and works just fine.

I'm using MuseScore 4 on the PC and want to use a MIDI monitoring program (Pocket MIDI). However MuseScore and Pocket MIDI will not connect simultaneously. It's one or the other, but not both.

What an I missing here???

MIDI Connection Issues

Bill Fischer — Sat, 21 Sep 2024 19:13:22 +0000

For the life of me, I can't get MIDI settings correct on several programs that run on a PC.

I've tried MuseScore, Bandlab (Cakewalk) and several other programs. Using a USB-to-MIDI cable removed link

I HAVE gotten a program called Jammer to work just fine, so there should be no hardware issues

Jammer is a program that generates backing tracks for songs you enter.

It's VERY old (like back into the mid-80's) and is no longer available.

I'm trying to connect from a PC to a Yamaha Clavinova (CVP605)

Any how this is driving me NUTS!!!

Looking for any advice/help anyone can give. Thanks
