Machinedrum SPS1-UW OS 1.70 Released

Machinedrum SPS1-UW OS 1.70 :rocket:

This is an unofficial firmware release and marks the first new MD firmware since 2012.

Our mission is to fix long standing bugs and enhance the MD’s MIDI Spec.

Download link and change log can be seen here:
Machinedrum_SPS1-UW_OS1.70.zip

β€”

The improvements to the MIDI spec allow for better integration with attached MIDI devices, such as the MegaCommand.

For those unfamiliar, the MegaCommand is a small, open hardware MIDI controller that provides the MD with modern sequencer capabilities and other great features.

Interesting. What does this offer a non MCL user ?

astonishing is the appropriate term indeed.
does that mean per track pattern length could happen ?

great to see someone is still taking care of the MD.
Thank you for that.

I tip my software engineerβ€˜s hat to you and I donβ€˜t even have a Machinedrum… …yet.

Wowowowow

Also curious to see what this bring to the table if you don’t have a mcl.

Much respect for putting in the love.

The changelog is part of the download for all those interested in what changes this brings… very rad and congrats to the two devs!

β€œThis piece of firmware is o.k”.

In fact, it just keeps getting better.

Awesome news! I’m hoping someone @Elektron can offer you some assistance in your future efforts.

Does 1.70 already have some notable bugfixes?

Thanks again!

On receiving SDS sample dump, MD user interface no longer locks up.
This will make MD more sample-capable and tighten the workflow (without having to reboot every time after receiving).

Awesome! My MD is only a lowly mk I so dont use samples much due to lack of storage, but I’m sure this will be appreciated by many.

Great choice of word … this is amazing!

Could someone post the change log ? Cannot open the zip on the phone and I’m too curious…

    βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’

This is an unofficial firmware release and is not
affiliated or endorsed by Elektron.

How to upgrade:
βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’βˆ’

  • Hold down the [FUNCTION] button while powering up.
  • This should take you to the Machinedrum boot menu.
  • Enter the β€œMIDI Upgrade” mode by pressing [5 LT].
  • Send either the SYSEX or the MIDI firmware file to the Machinedrum.

To transfer the SYSEX file we recommend using C6 βˆ’ Sysex Tool by Elektron.
After starting the transfer you should see the trig LED’s lighting
up, and when the update is done the unit should reset itself and
boot the new OS.

Detailed instructions are available in the EARLY STARTUP MENU chapter
in the latest Machinedrum users manual.

PLEASE BACKUP ALL USER DATA VIA SYSEX BEFORE UPGRADING.
BETTER SAFE THAN SORRY.

$53 | Kit dump request ID
%0aaaaaaa | Send kit number %0aaaaaa ( 0 to 63 )
If kit number >= 64, the current unsaved kit data (workspace)
is sent.

SYSEX kit sysex dump:

MIDI Byte | Purpose

(SYSEX init)|
$52 | Kit dump ID
$04 | Version
%0aaaaaaa | Kit originalPosition %0aaaaaa ( 0 to 63 )
If kit number >= 64, the kit is copied to the current
unsaved kit data (workspace)

*KitDump format below V4 is no longer supported.

SYSEX status request:

MIDI Byte | Purpose

(SYSEX init)|
$70 | Status for parameter %aaaaaa (see list below)
%00aaaaaa |
%0bbbbbbb |
$f7 |

Well this is one thing I didn’t ever expect to happen. Baffled.

*Eats hat for all the times I’ve posted there are not going to be MD or MM updates ever.

Wow, impressive stuff! I’m really interested in this kind of tinkering, and had been trying to work out how to get the firmware out of a Sysex dump - I came across your thread on the MAME repo where you were discussing this topic.

Would you be open to discussing further how you did this (either in public or private) or is it something you want to keep to yourselves? I’m mostly just curious and have a few ideas I’d love to implement - I’m an experienced audio software dev but haven’t worked with assembler so it would take me a long while to get up to speed, but I’d love to learn more and perhaps contribute to your project. No worries if you’d rather keep your methods private for now though, I would totally understand.

Wow! Can’t believe this! Awesome
