Hi, I know this theme is a little bit complicated, but it's only a question of possibility: If tracks are setuped with Transpose / Arp Mode option, they will change the playing behaviour, dependent of record notes while using record in one track. That's a bit confusing. Consequence: I've to turn every "Transpose Mode" track to normal or turn all other channels to "Mute", to record a track while playing. I don't know if it is possible, but could the Track Mode setting switch to NORMAL Mode for every channel while we stay in record menu (or maybe ignore the different Track Mode settings). After leaving record menu it should switched back to the last options. Best Regards, Rio. Besides: Which *.inc-file and which function controls the playback of seq for different track modes?

great video... cool ;)

ok, after i've done a real short crashcurse in pic assembler and a bit knowledge of c64 asm too, i think i got it (<joke>...wenn man net allet alleene macht ;) hehe</joke>): CS_M_RECORD_NotifyEvent_SLoopSnd ;; Rio Code, check SEQ_RECORD_MODE_STEP and SEQ_STATE_RUN btfsc SEQ_STATE, SEQ_STATE_RUN btfss SEQ_RECORD_MODE, SEQ_RECORD_MODE_STEP ;; endRio Code call MIDI_EVNT_Send Simple and now it works.. In attachment there is the whole cs_m_record.inc file. Best Regards, Rio. cs_m_record.inc cs_m_record.inc

they will get pretty warm after a while;) great to hear it's working now..

In REALTIME MODE or STEP MODE - every note from an external device will be routed to the defined channel to midi-out. Thats allright and useful, but in the case i want set up notes in step mode via external keyboard, while sequence is playing, my suggestion is that incoming notes shouldn't be routed (played) immediately to the device. (at time it's a bit confusing and disturbing listen to the sequence while doing this). So my question: What can i change in code to check whether Sequencer is playing and Step mode is activating to supress routing of incomming notes? The problem is, i havn't skills in ASM -- it should be something like this, abstract in c: if (!(seqplaying && stepmode)) route_recnote(); Greets, Rio

please upload software again first!!! if necessary upload MIOS again.

so i hope my background noises are ok. Another thing: if i've connected the bipolar psu and if i switch power of C64 optimized PSU on, then i can measure 11V on CV1 (FRQ1 or FRQ2), while core is booting. ... after 2 seconds it turns back to 6,3V without activating F2V. After activating F2V in application, everything is in the correct Voltage range. But, would it be alright that 11V are feeding for a short time (2seconds) to the C.V.s of CEM3378, or can this higher voltage level damage the C.V. inputs of filter, while doing this boot..? until now - everything works well. Best Regards, Rio

I've readen something in the SID Schematic about 22nF for filter, but i've stuffed the sid like in sid-boardv3: mbhp_sid_v3.gif with 6,8nF. What is correct and what is the difference? Besides, Mike is sending still 6,8nF capacitors for SID boards... I've found that posts: http://www.midibox.org/forum/index.php?topic=9132.0 http://www.midibox.org/forum/index.php?topic=2777.0 I havn't found a real reason or a declaration, why i've to exchange my 6,8nF...but are changes listenable and will be worth the trouble? On the other hand, where i can get this 16x Mylar Radial 0.022uF 100V 2% Polyester Capacitor in germany or does someone have some left in my country or in the near? Greets, Rio.

if i turn up the volume without routing signals through both filter and without activating a LFO, i can listen to 2 types of sound: - continuous repeating noise (sounds a bit like a railroad ;) ) - and another small hightone sound, which comes and goes sometimes... and sometimes the small notes rises or fall in a ocillation... ..all in very low level, but i'm not sure, if that is normal. The filter is working correct. I've notice, that IMHO the filter will only take effect at CutOff Freq > 1.0V. so i've adjusted C.V. between: 1.0...5.0V for frequency I noticed too, that CEM filter not really match with parameter of SID-Filter. So SID Filter will not take much effect in lowpass-area anymore, because the CEM filter is too low/deep... seems SID filter will be a bit useless vs. CEM, or? Greets Rio.

ok, after adding 10k trimpots and doing few fine adjusts... (oh that was a bit complicated) i got 0...5V for every AOUT Channel. The Datasheet of CEM3378 was a bit confusing, because i've readen that the frequency should be controlled between -150mV .. 100mV, but the description tells me too, that all inputs can controlled between 0..5V (*confusing*). So i checked both and 0..5V is working for frequency. I've connecting 5V to GAIN, but there was no need to connect 5V to PAN (should be mixed to Channel A = 0V) ok, only 2 little questions: 1. The filter is working fine. I only mentioned that the resonance turns into distortion if i move the resonance knob up to value = 100. Is this normal? (Maybe there is to much gain - i could add a trimpot for Gain too..) 2. If everything is silence, i can listen to some background noise (sweeping noise). Is this normal too? Greets and thx's for much support, Rio.

ok i'll only connect 5V at Gain and PAN and pray that them working...

ok you mean i should directly connect 5V to GAIN1 and PAN1 (GAIN2 and PAN2 too), right? that's something i don't understand, because i've build up by using this schematics: http://synthtech.com/cem/c3378pdf.pdf http://www.st-andrews.ac.uk/~jcgl/Scots_Guide/datasheets/Opamps/072dia.gif there isn't any resistor between TL072 negative input and CEM3378 output.. on the other hand, you said: ...but it's connected to negative input of TL072. so do i need then really a resistor, and if yes, which resistor type/value i've to take? PS:Beside i'll take a look at OPL3 Opamp circuit... Best Greets,Rio.

yes thats a fact! I havn't bought a 7-pin port and have used a desoldering iron for a damaged C64 board.... Oh man it spends a much off time to do that... the pins are fixed at correct position... so they matched in 7-pin port too.. greets, Rio.

ok.. only that i get it sure and to clear it up: 1.What should be connected to GAIN1 and GAIN2 and PAN1 and PAN2.. ? At time nothing is connected to GAIN or PAN 2.where should the 10k trimpot added on that CEM3378-PCB? til now, the board (shown above) doesn't work yet. I can't listen to any sound on signal audio out. please understand me...I don't want to experiment, if i'm not sure what i'm doing...

1) you need an own C64 psu for your mains voltage in your country!...don't use that european 220V!! 2) the bottom pin should be ground, all the other like in description here: http://www.c64-wiki.de/index.php/Netzbuchse (german) - but get sure -> take a measuremeter and check Voltage of pins between ground. but do it with a steady hand. test it only with an "canadian PSU". 3) it's best solution to use the optimized PSU schematic with one psu. 4) best you connect the few parts of C64 optimized psu schematic and connect core to sid board. then check the voltage at IC, without stuffing SIDs. 5) yes you need a DINX. Connect one rotary encoder and connect ground like in description of DINX. Scroll down this site. At bottom you find all necessary documents: http://www.ucapps.de/midibox_sid_manual_hw.html i hope it helps... Greets rio.

they are never used before... and same type R4. I get only in trouble with R4. I'ven't checked on a real C64...

i have done a PCB-Layout for 2x CEM Filter... here is a screenshot and the PCB for eagle light (in zip) in appendix. Please take a look what i've maybe forgotten - i've strictly orientated by schematic.. For all other, who read this: I can't give guarantee for any errors. Power connector from left to right: -12V, -5V, GND, 12V Signal Out from left to right: Left, GND, GND, RIGHT Yes i havn't connected trimpots or any signal to "gain" or "pan" and nothing is connected to them. (could that be the reason, that i can't listen to any sound?) CEM3378_handmade.zip CEM3378_handmade.zip

sorry, i haven't used different ensemble to much yet...

they are completly unused... and both have the same behaviour - only in HP area, i can listen to a bit sound.

ok, i'm able to control the AOUT_LC Voltage from SID Application Res and Cutoff endcoders, but how can i adjust the trimmer correct for AOUT_LC module? What should be adjusted first - the gain or the offset - and which values should be set? (I'm not really sure, i think they all work between 2,8V...8,xV at time - they are all standing in middle position). i've connected the CEM Filter Board to the AOUT_LCs, like in schematic of CEM3378... ... but at time i can't hear any sound. It seems that the power voltage is correct on every IC socket. What could be the reason, that i don't hear anything? The "Gain"- and the "PAN"-Input are not connected and opened. ...is that really be necessary or would be nothing heard, if i let them opened? Which type of trimpots you use (10kOhm ok)? Greets Rio.

IMHO: Ensembles should only be changed by up/down buttons.... (I deadjust continuous the ensemble because of using menu encoder for other purpose!..) Greets Rio.

Are we able to clone or does it makes sence, if different setups (6581 / 8580 + AOUT_LC) are used? Does someone have an idea, why my 'both' 6581R4 are soundless while activating filter? Best Regards, Rio.

@tk: I've the SID V2 application running on a second device with a 2x16 LCD (So i switched in mode 4 in asm). The problem is following: 1. if i rotate the "depth" encoder of LFO, it will not shown on Display (the LCD switched not to the correct visual position). 2. the main menu shows a ">" on the right side. But i can't choose the menu options because the "menu" encoder will change the "ensemble". 3. Filter: ------ Why 6581 SIDs are pre-defined in asm from 000 to 600? Hiigher values than 600, will change the filter too, at my 6581R3 and normal 6581 SIDs and gives more range for LFOs... 4. Filter 6581R4: --------------- if i use 2x 6581R4 SIDs, instead 2xR3 -> nothing will be heard on same SID boards, if i activate Low- and bandpass for both sids. only in HP area some noises are noticable.. Is there a reason for that behaviour? Someone notices the same? 5. Volume --------- is it possible to give the volume more range? If i activate them with LFo, i only notice very small changes (independent from sid type)

mhh...sounds a bit complicated, but i've to check out..

great application.. i'd checked out the box last weekend. I've only a question to the matrix (for easier work): it's possible to pre-selected the assigned EG or LFO, while pushing the horizontal buttons of the matrix (like in old application)? so that i've a direct access to current activated option.
