Hello, everybody.

Will "Xotic" Robotalk be a complete copy of "Maestro" Filter Sample/Hold? :hmmm:
I think it to be an original circuit.
Do you know anything more about a circuit?

Did anyone ever get a look inside of "Xotic" Robotalk?

Thanks.

I owned a Robotalk, some months ago ... just a plain Maestro FSH copy, that's all.
Has some nice sounds but the controls are really bad!

Hello!!

>to Chas Johnson.
Oh~~~!After all... :cry:
I felt have a small board size that it was another circuit.
Will the sound be the same?

I don't mean to derail this thread.
Stomper is well known to us here but, we cannot access the site or become members.
Any chance some here could get access?
I read many good things about your site on Blog pages. 8)

I would suggest trying a tonepad FSH-1 as the controls are more defined. It uses two dual opamps, and a lm13600 instead of 2 ca3080's. The layout has the max1044 on it for you as well. :D I still have to debug mine though. :evil:

I found it did not sound at all as organic as my 2 Sample & Holds, but then again mine are from 1975? so the values of the components have drifted all over the place I imagine. I also found the Xotic controls to be useless, I think they did too, it's discontinued, I believe.

For those who want to try the Maestro FSH, there's of course the info on GGG, but moosaputamus has made a smaller pcb layout which can be found here:

Links are in the text and layout uses the GGG schematic.

Here's 2 other layouts for the Maestro FSH, the ustomp version is the standard FSH while the tonepad version has some mods....

regardless of all the older version's anyone willing to put some guts shots up of the xotic robotalk so we can have a look. Xotic have some nice gear would be nice to have a peak in this one.
