problem mbseq V2 to V3

[matoz]

Hello all,  I have a problem: Seq v2 worked very well, yesterday evening, I install version 3 with pic 4620 and 2 modules IIc. And there, I have almost all Led who start to flicker in a strange way  and can' t sending a sequence in Sid. However, by defect,  the piste1 wrote in the seq which sends a bit on channel 1. The sid does not receive anything. however, on screen and DIN, I have access to all the functions, and it seem to be very good… Moreover, I would like to announce a small inaccuracy on module IIc on mbhp_iic_midi_v3.gif, the flat part of Led should indicate - and not +, which was a source of error…

If you put the 452 back in there does it work OK?

Did you add the pull-up resistor (R12) for the IIC modules?

Have you performed the midi troublehooting?

Did you try re-uploading MIOS and the seq application?

I remember, that last time a user reported such an issue, he used an older MIOS Studio version which doesn't upload the complete application.

So, please make sure that you are using MIOS Studio v7.5 or later.

IIC_MIDI, shown LED polarity in PCB overview pic: will be fixed soon

Best Regards, Thorsten.

thanks for answers :)

If i put 452 back, it works very well.

I added the pull up resistor for IIc.

I think i founded the problem: IIc' ID are all 00, i saw we must change Id of first IIc to 10. I tryed to change it but no results: IN&OUT of PC to IN&OUT of IIc

Midi events go out by midi out of core.

Now i have the following problem since seqV2 to V3 and back to V2:

Sid' s Led sometimes  flicker (less than seq, just a little). sound is correct.
