TK.

I don't know the modifications which have been made, but they should be more or less the same. Best Regards, Thorsten.

It's better to trace SID register changes with a tool like SIDdump. It not only gives you the oscillator settings, but also an hint about modulations and wavetable sequences. Some infos can be found here: http://www.ucapps.de/howto_sid_wavetables_1.html Best Regards, Thorsten.

Yes, should work ok, but it could make sense to use a low-drop regulator instead of the 7805, so that the unusued power won't be transfered into heat. Unfortunately I cannot give you recommendations for "known good parts"... Best Regards, Thorsten.

The MIDI output looks as expected, what is the actual problem? Best Regards, Thorsten.

So far I remember, for the rewind and forward button no LED function is available. Best Regards, Thorsten.

Hot tip: MIDI events are sent with "MIDI_EVNT_Send", this is a useful keyword when searching in cs_m_record.inc Best Regards, Thorsten.

For my own interest: could you please measure the DC voltage at following outputs: IC3, O4 IC3, O3 IC5, O4 IC5, O3 Best Regards, Thorsten.

Clever! :) Best Regards, Thorsten.

Hi Bacjonjuice, welcome on board! :) It seems that the pull-up resistor for the CAN Rx input is missing. More infos here: http://www.ucapps.de/midibox_sid_manual_ki.html Bst Regards, Thorsten.

Without loosing to many words: so long the green LED doesn't lit, the PIC16F88 firmware is not running. Possible reasons: +5V/GND (Vs/Vd) not available at PIC (check voltage between pin #5 and #14, should be 5V), crystal or 15 pF caps not soldered properly, firmware not burned correctly (probability low)... Or is the green LED not connected correctly? (check 220 Ohm resistor and polarity of LED) Best Regards, Thorsten.

Fine! :) No, encoder functions are not accessible via remote. But if you would add just one DIN shiftregister, you could control the current selected value with the "datawheel" (main encoder... the big knob in the middle) Best Regards, Thorsten.

According to the IIC spec, it is allowed to omit the STOP so long the same device is accessed again, but I felt saver to show you an example with stop/start, as I know that e.g. the IIC slave of PIC16F88 cannot handle the "restart" condition properly Best Regards, Thorsten.

Yes, it should start playing so long the BPM generator is in auto mode, so that it automatically switches to MIDI clock slave. I'm not 100% sure if this is the default setting in EEPROM, but it should... Best Regards, Thorsten.

fixed in RC12 Next bug, please! :) Best Regards, Thorsten.

The code looks correct. But the datasheet says, that there is an address pointer which will be incremented on each read operation. It isn't explicitely mentioned, but I would expect that you need to reset the pointer by hand when you want to read from zero. So, the code should look somehow like this (quick hack, errors can be expected) MIOS_IIC_Start(); MIOS_IIC_ByteSend(0xd0); // slave address, write operation MIOS_IIC_ByteSend(0x00); // set address pointer to 0 MIOS_IIC_Stop(); MIOS_IIC_Start(); MIOS_IIC_ByteSend(0xd1); // slave address, read operation b0 = MIOS_IIC_ByteReceive(); MIOS_IIC_AckSend(); b1 = MIOS_IIC_ByteReceive(); MIOS_IIC_NakSend(); MIOS_IIC_Stop(); [/code] once this sequence is working, you can add all the robustness stuff, like check for BS_AVAILABLE, etc Best Regards, Thorsten.

Yes, the red marked key combination remote+menu key has a special function, because it allows you to jump to the red marked menu pages. With key combinatin I mean, that for the menu page selection you have to press&hold the remote, and thereafter the menu key in addition. Thereafter press GP#1..GP#16 to enter the corresponding menu page. The order in which you release the keys doesn't matter (I just have doublechecked this, it is still working like expected). For the black marked key function you only have to press&hold the remote key You can always exit a menu page by pressing remote+"step view" keys In general the mechanism is working like the MIDI remote function of sequencers like Logic Audio or Cubase Just only keep in mind, that the remote key has to be pressed+held first! Best Regards, Thorsten.

RC11 contains just another fix for sustain pedal (wrong note was sometimes forwarded to oscillators) Best Regards, Thorsten.

Unfortunatly I can only say, that increasing the voltage won't help. JDM is known for such issues with newer PICs... Best Regards, Thorsten.

You are using an older MPLAB release where PIC18F4685 is not supported? Or you selected the wrong PIC? However, I don't know what you mean with "quickbuild" - the fastest way is to use MPASMWIN directly, and here you shouldn't notice such issues. Best Regards, Thorsten.

Hi, no, these menu pages don't exist in MBSEQ - there isn't enough code space for such features. Best Regards, Thorsten.

There was some confusion about the octave in the past. Problem is related to my unsorted programming habits. ;-) There are no special requirements beside of selecting the right MIDI channel. Did you already try the C key one octave upper or lower? Best Regards, Thorsten.

Hi, no, the engine selection is not the same like the four SID switches. With the SID switches you can switch between the master and the three slave cores. Each core can handle any of the four engines without uploading a new firmware. Best Regards, Thorsten.

I guess that you mean self-oscillation instead of distortion. Yes, a trimpot should be added to resonance as well. Set resonance to maximum (255) in the MBSID CS, and tweak the trimpot until the filter starts to oscillate. Thats the best setting. Some additional background noise is normal, but I don't know what you mean exactly with "sweeping noise". If for example a LFO modulates the CutOff frequency, you would notice some "sweeping noise". Best Regards, Thorsten.

The picture remembers me that there is still no OMG parameter available... Hm... Oscillator Magnitude Gigantomator? ;-) RC10 is now available. Rutger: the sustain pedal should work better now. I was able to reproduce the issue. And I added some more code to differ between normal and arp mode. I hope that it now works like known from other synths. Other bugfixes/improvements: EXT inversion flag displayed again, increased minimum FIP slew rate for better response on slow modulation with large value changes, and positive curve is working like expected again. Best Regards, Thorsten.

RC9 is now available with the very very very last feature for the v2.0 release ;-) (if bugfixes are required, additional RCs can be expected of course) o added optional FIP option (Filter Interpolation) which smoothes CutOff changes. It is especially useful when CutOff is changed via CC (-> low resolution) to reduce the steppiness. The option is not useful when the CutOff parameter is modulated from a fast LFO or envelope (on the other hand: it produces interesting effects in such cases ;-) [/code] Best Regards, Thorsten.
