Seems there is a set of occurrences necessary for a layout to appear in Q&A.
- The target device has to be controllable by MIDI
- The MIDI documentation is available, or someone is dedicated enough to puzzle it out
- Someone invests time to build the layout
- They are willing to share the layout
This natural filter seems to favor older boards, especially ones that provide complete documentation. Roland still provides extensive sysex control and detailed documentation for many new products, for example.
We got a request for a layout for a a particular device. Unfortunately, the documentation is almost non-existent. None posted on the mfr website. One found by searching just says it will send Sysex messages to store and real presets, and panel controls send Cc messages which can be recorded and played back. I have built layouts cold, never seeing the target hardware, when they are well documented and I am familiar with what the mfr really does (vs what the documentation says). Ain’t happening here. Someone may eventually document the messages, and maybe post them.
Jupiter X(m) and RD-88 are two current boards. I have built layouts for both. But now Roland have released an editor for the X(m)s. If they had not waited 18+ months after releasing the board, not provided complete Sysex documentation and control, and if lockdown had not provided endless free time, I would not have built the layout. I am still working the RD-88 layout, at least until Roland realizes their X(m) editor only needs minor changes to control the RD-88.
And once you start in a product family, it fairly easy to go forward. Big portions of the RD-2000 layout go directly into the X(m) layout. Then the RD-88 is just a mash-up of those two. Roland never throws away code that works.
With so many boards coming out with software tools, no need to invest time in building an MDP2 layout. But that is also why older boards do get MDP2 layouts - the mfr software only runs on Windows XP, and the last machine died. They like the board, so now is the reason to invest the time. MDP2 is really good at giving old boards new life - in some cases providing ability to control even when some of the front panel controls or display have died.
Another change is that mfrs used to rely exclusively on the MIDI for remote control. There is some shift to direct computer communications via USB or wireless, which takes away ability to control via MDP2 MIDI.
We have detects of layouts on the Facebook pages, Q&A, and help desk that never get posted. Look full featured and useful, but folks just don’t share them. I have messaged a few, and they are reluctant for some reason to share. I have had folks post extremely derogative comments on my layouts, so I understand. You do all the work, share for free, and some internet commando who would not know a Cc from sysex, even if it bit them on the rear end wearing a name tag, decides to trash it, and tell you how much better they could do, if they could be bothered to actually do it, which is beneath them.
And I know of three users that do layouts commercially - their product is not posted to share on the Q&A site. But MDP2 is mostly a labor of love, not sure anyone makes money.
The MDP2 team tries to help get past these hurdles as they arrive. As Dan has said, he has been doing this for 10 years, and it has come a long way, and keeps getting better. Many apps and even OSs have died during this time.
