MidiSizer 
Plz can you gimme the dimensions of the MidiREX? Just for searching for the best box for it…
Board is 4.8 x 3.1 inches, Enclosure height should be 1.5 inches inside.
thx!
Hi Peter, any chance you are making a few cases soon? Color is not important…Thank you! -K
The last MidiREX case i ordered came out almost perfectly, will make minor tweaks and order more. Then publish the design files. Lt me know if you’re in a hurry and ill send you current design.
hello! this looks nice. I dont know much about DIY controllers.
are the rotaries endless? and does this come with all the parts assembled?
thanks
thank you.
yes, rotary encoders are endless.
i offer pcb and pre-programmed mcu only, you can get all other parts using up to date BOM that has digikey and mouser part numbers.
Do you know a website with finished boxes ready to go, for the MidiRex ?
Nope, pls check Mutable Instruments forums for various options.
Ok, thank you.
Hello, Is it possible to write and run modified midipal firmware like this on midigal as well?: http://lauterzeit.com/midipal/firmware/ ??? thanks
yeah, midigal can run any midipal compatible firmware.
Hello, are there tutorials on how to get the MidiGAL up and running and assemble the missing parts? Thank you
Sure, check here:

Hi,
I stumbled across your site, I am very interested in your Midi Gal and I was wondering if you could answer me; does one unit can do all different features;arpeggiator, sequencer, clock etc or do I need to have a separate unit to do each thing (if I wanted to use all functions)?
Many thanks,
Dan
It depends on the firmware. MDIpal firmware has simple clock gen, arp and sequencer apps. However, full featured MidiSeq, MidiArp and MidiClk take up entire device, so you’ll need to reload firmware to have them. Reloading firmware requires sending a special sysex to it.
Thanks for your reply.
I assume I can also back/load up the midigal sequences etc back/from the computer (via sysex) if I was to load it up with a different firmware for a different use. Can you please confirm?
Cheers.
Sure, you can back up MidiGAL/MidiSeq sequencers at once or one by one via sysex to a computer, then load them back into current slot, or restore entire device.
Have a small problem in purchasing. I live in Thailand. Paypal refuses to accept my actual address. Is there a way we can arrange to have my goods sent here? I can pay to an email address. Thanks.
Email me at an address specified in the order pages and specify which pcbs/mcus you need and an email address to send paypal invoice to.
hello, sexy device overhere .. any vidéo with few synth playing chords , bass ..
record patterns, quantitize, shuffle, save, playing all parts without stopping ..
how long for france, yu think .. cheers
No video at this point, but i’m planning to shoot one at some point.
it is possible to use midiAlf hardware to develop a programmable midi controller ? that would be great!
how to proceed ?
Sure this is possible. Download the source code, from MidiALF page, install the tool chain, and hack away. You must be able to program in C++ though.
Hey where can I buy the pcb for the midiGAL?

Hello,
Is there an enclosure design publicly available (eps/svg) for MidiAlf, MidiRex or MidiGAL ?
Thanks for your amazing work !
I just finished a midiAlf and I plan to work on a midiRex 😉
Regards,
Dimitri
Yes for MidiGAL, almost for MidiREX, in works for MidiALF. Please contact me via email for details.
Hi, I’m hoping you can help me. I’m trying to turn a two voice synth plus two mono synths into a polysynth.
I’m looking for a device that will take 4 notes from a master keyboard (in a 4 note chord) and split them across channels – however I need the first two notes to go to the same channel (eg channel 1 for the two voice synth) and the second and third notes to go to their own channel (eg. channels 2 and 3 for the mono synths).
Any help would be greatly appreciated.
I don’t think this is possible without custom firmware programming: both MIDIpal firmware and dedicated MidiDispatch firmware will split notes between given amount of channels evenly.
Hi
I was wondering what combination of midi sequencers would work for 6 poly midi tracks plus a few CV tracks. Randomization and other effects would be nice also. Thank you for your time
Not enough info — can you please be more specific about the task you are trying to solve?
I apologize.
I have a Nord Lead 3 which I will be running 4 total midi tracks from, each step with 2-3 voice polyphony. I will also be running 2 midi tracks out of a drum machine. I also wanted to sequence CV tracks from modular gear.
What combination of midi and CV sequencers would be most beneficial to run this setup?
Hopefully that explained it 🙂
Hmm… are those 4 tracks from NL3 monophonic or polyphonic? Same question about “two midi tracks ouf of a drum machine”. What exactly do you mean by “sequence CV tracks from modular gear” ?
Hello, i own a midipal and do i read it good that with some limitations i can load the midiarp sysex firmware into the midipal. Thanks, looks great.
Yeah, MidiARP will run on MIDIpal, however it may be difficult to use without a switch. You’ll also need an AVR IS programmer to flash the firmware as regular sysex upload wont work.
Thanks for the reply, can i use a FTDI adaptor or do i have to use an Arduino isp,
and connect it to the isp on the midipal-board.
Arduino ISP may work, however i have no experience with it.
And can i ”make” the switch myself, which pin it uses? Thanks again for the reply.
Sure you can: MidiGAL switch uses PB4/MISO pin.
Hello, trying and doing uploading the hex code from midiarp.hex i bricked the midipal.
Yeah these things happen when you like to experiment.
Looks like, after a search, that i somehow changed the clocksource so it says
‘device id 0x00000’ so in short it is not to be recognized anymore because it is not running, because it can not run without a clock.
So my question is do you know where to find the xtal pin on the pro mini chip
hosted on the midipal board or even better the location of the pin for xtal.
Cause then i can unbrick it with an external ocsilator, exiting.
Thanks in advance, Dian
You can probably just lower the frequency at which the firmware programmer talks to the MCU to the lowest available (i think it’s 125Khz), so it will be able to talk to the MCU running at internal clock. Then you’ll be able to program fuse bits for the MCU to run at external xtal.
Thanks i got it working, it seemed bricked but a few days later i uploaded and it was allright
with good fuses.
Still wil try to upload midiarp, better upload your boot hex and load the sysex by midi.
Dian
Hi,
Is there a way to sync two Volca FM to double the polyphony with your device? I don’t want to just duplicate the signal, I want to be able to double the voices (play up to 6 different notes instead of 3)
Thanks
Yeah, you will need MIdiGAL with MidiDisp firmware that can dispatch MIDI Notes to polyphonic sound modules. This firmware is not publicly released yet, but is stable and a bunch of people with advanced dispatching needs used it w/o problems. Please contact me at the email specified on the ordering page and i’ll provide you with more details.
Hello, where can I find plans for a midirex case ?
is there a possibiltiy to get a pre assemlbed midi rex ? all the best, dom
Sure, please contact me using the email address space specified at the ordering page.
Hi! really nice projects! I have no building skills, so is it possible to buy a ready-to-go MIDIGal from you, complete with case? If yes, how much it cost? how much it takes to be made? thanks!
Sure, fully assembled MidiGAL with firmware of your choice is $145 plus shipping, which is $5 in the US, $15 to Canada, and $25 pretty much everywhere else. Usually it takes a few days, however right now I have a ready to go MidiGAL, so it could be shipped next day.
Hey mate, would love to order a pre-built Midi Sequencer from you with CV/Gate for controlling modular & synths. Not sure exactly what product to go for but had my eyes on the MidiAlf. Can you hit me up with prices, options, build times etc. ❤
Please contact me using the email address specified at the order page https://midisizer.com/midialf/ordering-midialf/ and we’ll figure out how to proceed.
Hi there!
Do you have a device that can merge multiple channels multiple times? As in, creating multiple groups of merges channels?
For example, I have a device where I’d like channels 1, 2, and 3 merged into a single channel, at the same time as merging channels 4, 5, and 6 into a separate single channel… and so on.
Best regards and keep up the great work!
Barnaby
No, not multiple times. MIDIpal has merger app that merges several input channels into a single output channel.
Could your please describe what you are trying to do and if there is no better way to do this, I may be able to create such a firmware for MidiGAL.
Hello, awesome site and projects. I’m sure something here can help me do what I want to do. I want to be clear so I apologize ahead of time if I give useless information. So I have a keystep pro controlling my volcas and Jupiter x. I try to engage remote keyboard on my Jupiter to give the keystep access to the I arpeggio, but doing that takes away my ability to choose a midi channel and my Jupiter ends up receiving and playing the midi sequences I have going to the volcas. I need to be able to send midi from the keystep to a device that can filter out at least one midi channel (although unlimited midi channel filtering would be perfect) so it doesn’t get to my Jupiter. Would the midigal work like this?
Yes, MidiGAL with MIDIpal firmware, running the Channel filter (chnfiltr) app will allow you to filter MIDI channels.
