TM3030 PIC Versions

I still have the v1.1 PIC in both my TM's, is there any need for me to change it? I read here a while ago V1.2 allows midi control of the filter or something like that?

Any info appreciated...

There was a later version that Colin did for the issue 2 and issue 3 boards. Along with some changes to the TM3030 circuitry the new PIC allowed the modulation wheel midi CC to control filter cut-off.

These later PIC versions can be used on issue 1 boards. However, if you wish to make use of the additional filter control you need to add a bit of simple circuitry as shown here:



It is possible to add those three extra components on the underside of the board too without need for any stripboard.

However, the TM3030 is a legacy product and no new boards will be produced. I have asked Colin for some new version PICs for spares but these are not in stock as yet.

Ok, thanks for the info. Is there any other benefit to having an upgraded PIC?

I would not have thought so.
