3 Manual VPO project by novice
Well I am finally starting this project which I hope to have ready for my partner for Christmas.:eek: I am a total beginner with music, electronics and programming so what could go wrong!
I have an old Midi electric organ (Rodgers C-445) that no longer works so intend to use the cabinet, stops. manuals and pedal board to create my virtual organ. I will end up using Hauptwerks.
I am still in the process of sourcing a 3rd manual so I will hopefully be able to have everything else set up and then just plug the last manual in when I can get one. Ultimately I should end up with 3 x 61 note (matrix) manuals (utilising existing ribbon cables), a 32 note pedal board. 2 x expression pedals, approx 40 backlit stops and a couple of potentiometers.
I have a soldering iron and digital multimeter. (if there are other "must have" tools, please let me know.) I also have the original wiring diagram for the Rodgers organ.
I have stripped all of the original circuit boards from the console and once I finish doing the initial testing of my 3 x midi cpu's I would like to start with the wiring of the manuals.

Introducing the MIDIWidget MIDI Decoder
The MIDIWidget is a new MIDI decoder that replaces both the MD24 and the MSA series MIDI decoders.
http://midiwidget.com
The MIDIWidget has both USB-MIDI I/O and traditional 5-pin DIN MIDI I/O. There is also a new "configurator" app for Mac and Windows that replaces the sysex configuration method of the older decoders.
Here are some additional features:
- Powered by USB, or can operate independently from computer using battery or other DC power supply
- Responds to input via USB or by traditional MIDI (or both simultaneously)
- Standard MIDI In/Out/Thru ports
The MIDIWidget was originally announced as a new version ("Rev H") of the MD24. As of this writing, beta-test units have just been shipped.

Yamaha PSS 280
Hi,
I've seen an example of a UMR working with a PSS 270, but never seen an example of a UMR2 working on a PSS 280. I just happen to have two 280 lying around, and would love to get them working with midi.
I have also seen a reference to the PSS 280 in the discontinued UMR support page, posted by "BentApparatus" quote follows:
"an interesting one is the PSS 280 which is a "preset" version of the PSS 380/390 same 100 voices(stackable by 2=500+ combinations) BUT no editable synth and only 20 beats, also its basically a more powerful
PSS 140(UMR compatible) maybe you should try to locate one John and see if its UMR gold! lol"
I'm sure someone else out there must have figured the 280 to work with the UMR2 and would really appreciate any guidance. I don't have an oscilloscope, and would rather not have to invest if anyone out there has already figured the matrix out!
Many thanks in advance.

MSA fixed-length pulse issue
T. is having a trouble with an MSA thus configured:
The problem here is that only output #2 is configured for fixed-length output, which is mode 02h.
The output config format for the MSA is "mm d0 d1". When mm == 02h, or note output with fixed-length pulse, then d0 is the note number and d1 is the velocity threshold to trigger output.
So for fixed-length pulse output from notes 60-67 (3Ch-43h), the config would look like this:
Set the MSA's dip switch to "all positions off" and power cycle it before sending the sysex above.
Code:
F0 00 01 5D 05 01
00
// output 0
00 60 01
// output 1
00 5F 01
// output 2
02 00 01
// output 3
03 01 01
// output 4
00 59 01
// output 5
03 02 01
// output 6
03 03 01
// output 7
03 54 01
// pulse length (7Fh 7Fh = 8.2s)

Do I need a mode switch?
Hey there,
I'm trying to build my Highly Liquid Midi Retrofit into my Yamaha CS01 MKII.
The reason why I integrate the Midi Retrofit into the synth is that I want to receive Midi with my CS01.
So my question is: Do I need a mode switch, if I just use the UMR2 just for Midi-In?
Would be great if somebody could help me.
Best,
Nic.

rack Guitar effects switcher Build
Hi
I am new to this forum so hi to everyone.
I want to Build a rack switching system to similar to the GCX and patchmate. I have followed the Ipatch thread which is very interesting. I was wondering about using relay daughter boards from ebay
http://www.ebay.co.uk/itm/1306823261...%3AMEBIDX%3AIT
It says they have gold overlay silver-paladium contacts. I need the loops to have Input-send-return-output from looking at this relay board I think it will only sith a mono loop Correct or not?
Once assemble with correct relay boards/Buffers etc can the Midi widget funtion in the same way as a GCX or roctron units.
I have a load of boss, rack and true bypass diy pedals to switch in and out. I am also looking to Route singnals Between an AC30 and a Weber 5E3 amp.
Any help advice or ideas would be great. I hope to document the build

Roundrobin
Hi John I just received the midiwidget in good grace! Thanks for that. Also the app looks really good.
My idea is to use the midiwidget as midiwidget in a modular synth and once completed I would like to build a servo which will drive a drumstick. The minimum velocities I need would be 8 although 127 would be more then welcome. . The clock outputs are really nice to have to. If you filter them , correct dc offset and amplify them it will give you a nice tempo synced sine LFO. Or leave out the filtering for a synced square LFO.
I have an idea for 2 features to use in modular synthesis or with creative triggering in general. Round robin,
Let's say I assign trigger 1 to 4 to seq a1, seq a2, seq a3 and seq a4
Every time the note of trigger 1 is triggered it cycles true trigger 1 to 4
This could be use full for voice cycling. So every trigger sound different.
The other feature is to assign a range of notes per trigger.
Like this every range of notes could trigger a different envelope.
Cheers Tim

8 input for Expression Pedal project
I'm looking to build a 8 in module to use Exp. pedals on an Axe-FX.
so far. as i understand, the module have no problem to physically get 8 ins with 10K pots.
i have no problem to physically make it happen.
where i kinda get let lost is on the programing side on the thing.
I think i have to send a code to the units once build but what software do i need to have to do that and is there anything i miss if i say that physically all i need to do is to connect all ground to the G terminal, the ring with the DC regulated terminal and all other terminal (16 to 23)to the tip pin of my jack connector ?
( like Fig. 9.4 show )

Help with programming MIDIWidget
Hi,
I am a bit confused on some of the commands and operation of the MIDIWidget configurator program and would appreciate some help. I am interested in programming most of the outputs of the MIDIWidget to turn on (logic high) with a note-on, and off (logic low) in a specified number of milliseconds. Some of the other outputs will be like the note toggle command of the MD24 (on for a note-on and off for the following note-on); and the rest of the outputs I want to be on until a note-off command is received. What programming commands will allow me to do this?
Other questions are:
How do the 4 logic note commands (on/off; on toggle; on, fixed duration; and on, match only; work?
Does and X in the box mean that function is active or inactive?
What is control by preset and how does it work?
What is preset recall command and preset store command?
What is the grid to the right of the preset commands and how does one use it?
I would like to be able to store several sets of output configurations of the MIDIWidget and call them up instantaneously by sending a MIDI note number. Can I do this with the preset feature?
Thanks,
Jeff

Triggering solenoids
Hi there,
I'm a musician who knows nothing about electronics. I want to use the MIDIWidget to trigger an array of 5v solenoids, each corresponding to a MIDI note. How would I wire that, and do I need any extra components?
(I should probably learn something about electronics before embarking on this project but I'm keen to just get something working quickly).
Thanks for your help.

Roland TR66 midi clock?
I have a Roland Rhythm Arranger (TR66) and would like to modify it so I can play its patterns in sync. Is there a product that can be used for this job? I have been advised from synth service guy that it would be extremely hard because of negative polarities stuff, which I have no idea about. Anyway, is it too much trouble to be worthwhile. I was advised to look out for a CR8000, but I do prefer the sound of the TR66.

Introducing the EZMIDI MIDI controller/encoder
The EZMIDI MIDI controller / MIDI encoder has 64 switch inputs, making it useful for button- or switch-based MIDI controllers or virtual organ console builds.
http://www.ezmidicontroller.com
No programming is required. Instead, the EZMIDI "learns" what messages to generate based on a simple process of sending regular note, CC, or program change commands to the board.

Building a custom instrument with MIDI - which product do I use?
Hi everyone,
I'm new here (hello!) and a n00b so bear with me, while I get oriented.
I am building a custom instrument - a synth/organ that will be keyboardless but have MIDI input so it can be controlled with a MIDI controller on the PC or another keyboard.
Basically I am unsure what product to use to achieve the MIDI input. Can I get some advice?
The MIDIWidget looks very nice, but it doesn't have enough channels to do what I need (I need 36 key controls) unless it can multiplex - can it? The UMR2 I think will do what I need, for example I can build up my circuit to be analogous to the Casio MT-410 with a scan circuit and some data latches, and then interface the UMR2 to it. But it looks a bit more involved than the MIDIWidget.
Does anyone have any comments? What product might be right for me? Is there a way to squeeze out 36 notes from the MIDIWidget easily? Or is it the UMR2 that I need?
Thanks in advance for the help.

Newbie questions
Hey Moderators, John
Many thx for such a great body of work, that is the MIDI CPU!
would love to use one of these 'boards' for my next old skool midi controller project...
so been reading up, and poking around the forum for info...I have tried to read the 'manual' a few times
...and I can see how to hook up the buttons and pots ect....I can see that you dump a SysEx 'string' to configure what the pads do
Q, is there a APP for this, rather than having generate the SysEx manually, I did see a link 'http://sugarkick.co.uk/midicpu'
but can't find the 'SysEx dumping app' there, did you get your one done John??...
I can see you have 4 layers...I can see if you call layer 00, you can then stack the other layers on top, to give multiple events from the one trigger terminal.
this looks like any layer stacked on top of the one 'trigger term', happens at the 'same time'
Q, can I have the 4 layers work as, '4 banks' have them NOT trigger at same time....have another trigger or encoder to switch 'between' the 4 banks, so to have EX: 4 different 'layers' or 'banks' of CC numbers, and you select one 'bank' at a time, say one to control different synths?? A very handy feature on any master controller.... if it can't do that, then its a killer 'add' for the next revision... ;)
Midi CLOCK sync and transport controls Q,
if i configure a 'midi start / stop' button....do I have to layer up the 'Logic Input Trigger: MIDI Clock'?? so to be trigger at same time??
or are these not related, and I only need to trigger the 'MIDI Clock' command??
I want to 'clock' other drum machines or on board sequencers / arp...using a button
killer add for next revision... 16 note, step sequencer, that has 3 'triggers' that can be configured to:
'record', 'erase', 'next step'
and one 'pot' for tempo....
then if room simple arpeggiator...
;)
keep up the great work fellas!!
many thx
