Roland Boutique Sysex

[sompost]

Hi all,

I'm new to Roland synths and to this forum, so hello to everybody. And while we're at it: Happy New Year!

While playing with my Boutique JU-06 I discovered a few things regarding its MIDI implementation:

1. While everybody knows that the Boutiques respond to MIDI sysex messages to set patch parameter values, you might not know that they also respond to parameter request messages. So you can effectively tell your Boutique to return, say, the current value of its VCF Cutoff setting, which it will do by sending an appropriate parameter sysex message back to you. You can even make it return the name of the patch!

2. The patch dump messages that the Boutiques send when you switch to chain mode (or when you change a patch while it's in chain mode) contain more fields than are necessary for the Boutiques' parameters. For example, JU-06's LFO has two parameters (rate and delay) but the corresponding sysex message contains 7 fields! The same is true for all other functions. I wonder what these fields are for.

If somebody could post a sysex dump of a JX-03 and/or JP-08 voice, together with the patch file of the same voice (from the backup/restore folder of your Boutique).... Perhaps there are some surprises in these little beasts!

The sysex dump that JP08 sends when changing patch is quite easy to understand, comparing the PRM text file saved in the internal memory and the sysex list ;-)
Basically the parameters are the same of the PRM patch, with some ridundand data, probably left there for future use

Does this Sysex work with one device or two of them need to be poly-chained ?
[Quite remarkable thing that Roland did not publish the Sysex spec]

[paologatto]

they work for any number of devices, also only one. You have just to enable the polychain mode. If you have 2 or more units, get the midi sysex output from the last of the chain, and send the midi sysex input to the first of the chain
