Subject: Re: [Simmons Drums] SDS7 Program Selector Pad issues

From: <music@...>
Date: 2014-03-07

A test of the Selector Pad revealed that it is 100% functional. All pressure pads on the Selector work flawlessly.
However, on this Selector Pad, Pins 4 & 6 were Pgm 2 and Pins 4 & 5 are PGM 3.. which differs slightly from what Michael indicates below. (2&6=P14, 3&5=P7)
One of the SDS7s being tested with the Selector Pad is a low numbered early "white" connector version, and the other one of the last ones to be made. But I doubt they would have made a change to the Sel Pad pinouts along the way?

Here are my Sel Pad test results:
PGM     Pin   Pin
01           4       7
02           4       6
03           4       5
04           4       8
05           3       7
06           3       6
07           3       5
08           3       8
09           1       7
10           1       6
11           1       5
12           1       8
13           2       7
14           2       6
15           2       5
16           2       8

Next, I test the SDS7s

Cheers

The selector pad is only 16 switches. To check, ifthe SDS7 is working right, take a wire and connect (in the socket of SDS7) pin 4with 7 for PRG 1, 2 and 6 for PRG 2, 3 and 5 for PRG 3 and 4 and 8 for PRG 4.Then check 3 together with 7,6,5,8 for the next 4 PRG. Then again with pin 1together with 7,6,5,8 for the next 4 PRG. Then again with pin 2 togetherwith 7,6,5,8 for the next 4 PRG. Pin 9 and 10 don't have function. Clean thepins inside the selector jack.
To check the wires, remove the FSR and shortcut theMatrix X colours green-yellow-brown-red with one of the matrix Y colours white,violet, blue and black.
It is possible to clean corroded FSRs, but I don'tthink you need to.

I didn't realize that I had to remove the rubber that is taped down to thechassis in order to access the FSR contacts.... was hoping they would beinside the case itself. The chassis merely houses an Earth tap, a ribbonconnector to/from the FSRs, and a bit of shielded cable that exits out of thechassis to the SDS7. Huhn.

Before I attempted prying the rubber surfaceoff and risking damaging it, I tried the Selector Pad on a second SDS7... andwas surprised to see that Selector Pad buttons 2, 6, 10, 14 (basically, thesecond column on the Selector Pad) which didn't work on the first SDS7 workedon the second SDS7... however, pad buttons 9, 11, 13 which did work on thefirst SDS7 now didn't work on the second SDS7 !!!!

So, this points toan issue on the SDS7's themselves I would think. Either the connector on theback of the SDS7 cases or a component inside the Brains needingattention...

Thoughts?
