Boss VF-1 Effect Processor

I'm in SysEx hell right now...  I just got an Edirol PCR-50
controller, and I'm trying to get it control my VF-1 in realtime via
SysEx.

I created a Keyboard Multi patch today, and I want a knob on my
PCR-50 to control the Ring Mod Effect Level in the VF-1.  So I look
at the VF midi implementation chart, and here is what it says for
that particular parameter:

OFFSET(H)   SIZE(H)    DATA(H)
---------   --------   -------
* 01 28     00 00 02   00 - 64

Now, this is the first time I've ever dealt with this stuff.  My PCR
manual tells me how to send a master volume message by sending this:

F0 7F 7F 04 01 vL vM F7

That looks way different than what is given above for the Ring Mod
Effect Level... so what would the string for it look like?  Maybe
this?:

01 28 00 00 02 00 64

Somehow I don't think that's right.  I know this stuff is a pain in
the butt, but if somebody could tell me how to take the info the VF
midi implementation chart gives me and turn it into SysEx strings, I
would be eternally grateful.

Lava:

I tried to email you directly regarding VF1 patch editing software I 
am nearly finished writing that covers **ALL** VF1 algorithms, 
including Keyboard Multi. Unfortunately, Yahoo bounced the email 
back, saying your account was closed, lost in midi hell, etc :)  

Please email me if you have a PC/Midi setup, are interested, and have 
6-8 hours to dedicate to beta-testing keyboard related portions of 
the software (details of which I will explain in my response). The 
testing itself is simple but tedious. The upside, once done, is that 
I can pretty much assure you that your days in VF1 Sysex hell will be 
permanently over (free of charge, in the event Roland and/or people 
on this newsgroup care to pay me for my software development time). 
My original intent was to control the VF1 via PC, but your email made 
me realize the same software, with a minor tweak, would be useful for 
anyone doing what you are trying to do, i.e. programming controllers 
to run the VF1, without the Sysex details/headaches. 

As for your immediate question, I don't have your controller, but the 
following Sysex should control the Ring Effect FX Level, when the VF1 
is already set to Keyboard Multi, and with the Device ID set to the 
factory default (Device 1):

In Hex:
F0 41 00 00 23 12 10 01 28 00 64 ?? F7

In decimal:
240 65 00 00 35 18 16 01 40 00 100 ?? 247

Your controller should vary the 0-64hex (0-100 dec) for Level 0 - 100.
The ?? is the required checksum byte, which the controller hopefully 
computes for you. If not, or if you have problems, please let me know.

Hi, I'm interested.
t.

Hi,

Im not sure if this email is for me since it's a 
month old and that I dont know much about controlling
this unit throu pc.  

I'm wondering if you could answer this question for
me.  Can I use VF-1 as a keyboard synthesizer or is
the midi just for controlling it?  I can't seem to
make it happen.  I bought a demo model and have no
manual.  Thanks in advance.

No, the vf-1 does things to an audio signal and the midi is for controlling
the settings of the vf-1.
I remember I had the same question about midi years ago.

A keyboard synthesizer sends a  "Note On" midi-command while pressing down a
key and so the keyboard starts producing the sound of a chosen patch in the
pitch  that belongs to the pressed down key.
There is no way a VF-1 can send a "Note On" and "Note Off" midi-command and
trigger a synth or keyboard patch.
It is an effects processor, also it is good to realise that it has only  a
Midi Out and not a Midi Tru (but this is another but related topic).
