MS-plus hidden drum machine? #85
Comments
|
We already have a script to decode the patterns.... |
|
My memory was slightly wrong, it was an effect for the GCE-3. I guess (hope) this might work on MS-plus, but I'm a little too scared to upload to my new/expensive pedal. |
|
Not sure that the ZD2 actually does anything... it's code segment is pretty sparse. |
|
Trying to figure out remote control on the GCE-3, which has the '' effect. Installing Turn it 'on', but no sound... Can't seem to set BPM or Vol. Going to jump to Windows/GuitarLab to see what happens there. |
|
It looks like my GCE3 (as G1XFour) had unknown effect in the patch and it was NOT offering to install 'Rhythm'. Switched to GCE3 (as G3n) and could install 'Rhythm', but it is NOT listed in ZT2 and in fact it is using the longer/clipped file name "RHYTHM_100.z" This is seen as my gui code scans for files... I can install this effect into a patch (via midi commands), but not control it. GuitarLab would start/stop the effect as was enabled/disabled. |
|
I managed to grab and decode what GuitarLab does, it's 4x SysEx - looks like it's pressing then releasing the button. It seems that you need to press the correct 'slot' (where the RHYTHM effect it) for it to actually register. NOTE: it seems that the pedal is very sensitive to locking up here and not really working correctly afterwards. Going into GuitarLab and removing the patch seems to be the cure. |

Grrr.... took me a while to figure out preset selection via midi on the G3n Preset 150: And then I can start the rhythm with |
|
So here's a thing..... Gives us a selectable effect, which has dial/parameters that can be changed. The tempo follows the Tempo effect value... I just don't have a way to start the drums actually playing. :-( |

hi @mungewell I seems you are rediscovering independently what I did - and that led me to revisit. Here's my current understanding.
Example I have put a rhythm as physical slot 8. [[just to allow me to anchor slots]] I dont seem to be able to say "toggle FS8". WINDOW1 ... ... Demo next post |
|
So with WindowsStart.sh 5 Now we move alone one. So I knew I needed to "prime" the rhythm (and looper!). |
|
also - with the loop the subsequent control depends on holding a FS down for a set period - I was thinking some logic in the kit - but I am guessing it must be emulated in the Zoom Guitar Lab somehow |
|
The LP-MONO and LP-STEREO dont play nicely like rhythm or LP-MN2 and LP-ST2. For the latter - the stop buttons are the SECOND FX - kinky! |
|
I spent way too long last night trying to find a 'prime' and 'toggle' SysEx to actually start the Rhythm playing.... no success. I guess that it's either a completely different message, or that the pedal doesn't actually have a Rhythm thread/process running to receive the message. On the (real) G5n/G3n does the known message actually press the footswitch on other ZDLs, so that one would see another indication of it working. Or is it specific to the Rhythm/Looper? A good example would be 'Bomber' where the Foot-Switch triggers the noise.... |
|
I'll try to upload a video to YT later today with sysex and PIP video of the G5n. |
|
https://youtu.be/CMEuxgvYT9k?si=CXCInKx4COLNI3N_ I should rename my command to simply FS.sh [1-4] [01] And, depending on model, render FS and move them according to windowing. |
|
@shooking Thanks for the confirmation, and video. I don't think the 'Window' applies too much to the MS-plus as they only display one effect at a time. Thomas' page confirms that the 'move/display to XX' is slightly changed, and does work In theory the trigger would be similarly changed (with '03' indicating slot 0, of a 1 effect 'window'). Triggering the foot-switch was not working on 'Rhythm' late monday. I am trying again today, but with 'Bomber' effect, seeing if I can trigger the sound via SysEx..... still doesn't work for me :-( I tried changing the data value, but without luck. Neither command returns a SysEx 'ack'. |
|
So looking at @shooking script for the G5n, it's directly accessing the 'Effect On/Off' control - not 'pressing a fake' footswitch. If I do the equvialant on MS-60B+ it CAN trigger the Bomber effect when in 'Trigger' mode. I do have to do the 2nd one to turn off the LED and allow another sound to be triggered later. When using the real foot-switch the LED turns off automatically. It does NOT work with the 'Rhythm' effect. Manually pressing the button toggle's LED (but does NOT grey out effect), via SysEx doesn't affect the LED at all (even if already on). A short SysEx should respond with a read of a value.... it appears I can set it (on/off value) low, but then it's automatically set high; previous 2 responses buffered, 3rd response is the 'read'. If fact 'Rhythm' always reads a '01', regardless of what it shown by the LED. |

Perhaps (as I mentioned before) the task which generates the Rhythm sounds it not actually running on the MS-60B+. There are strings in the FW image which seem to relate to tasks, but that's not actually guarantee that it's started. It could be that the frame work is in place from the G2Four, and just not enabled on the MS-plus pedals. Maybe there's a configuration block, or bitfield determining this.... does the pedal have I2C/SPI memory for the serial number? Interestingly the only MS-plus to support USB Audio is the MS-80IR (so it means that the hardware is capable). |
No sorry it isnt. whereas RhythmStartStopWindow.sh So let's say I am at FX slot 9, windows slot 4 |
|
Ah, OK.... Must be getting old, one late night and my brain goes to mush. ;-) I had previous tried with the '0x0A' command, didn't work neither did any adaption of it. I think this ticket will be on hold for a bit. |
Glancing at hexdump of the unzipped FW, and it looks like both the MS-60B+ and the MS-200D+ have the table/patterns similar to the G1Four format
Although a drum machine feature is NOT mentioned in the menu. IIRC The G5n has a effect which can be placed in a slot in order to control it's drum machine.
