ah ok, now i got it ;) Thanks.

So I don't understand what I have to connect, when I want to use USB power. Does it need to connect to PSU-Circuit [J2 --> 3,3] too (as J2 INput?) or is it not necessary? And if yes, how I have to connect it correct, if I want to use my C64 PSU as a secondary supply. Your decription for the connection confused me, because I don't know, which way the 5V-USB Power have to go :D Greets, rio

hey thx for all your informations.

hey, you mean, i don't need extra LTC modules for that case? I have 4 IIC Modules. In my current box (V3), I have used 4 IIC + 2 addional LTC Modules to duplicate IIC Port 3 + 4. Now I have also 2 more LTC boards, but it looks it could be very close inside my case ;) - so yes i am interessted how to optimize my box maybe with left out LTCs, but with 4 duplicated MIDI-OUT Ports. greets, rio

Hello, this link/schematic http://www.ucapps.de/mbhp/mbhp_core_lpc17_output_buffers.pdf contains: So it is possible to connect multiple MIDI-OUT instead of using a lot of LTC-Modules anymore (for space-saving inside the case)? Or does it mean that LED output can be multiple only? Greets, rio

So it fits for my needs? Greets,rio

Hello, i want to use the 5V DC pinout of my C64 PSU to supply the SEQV4. So i want connect the 5V directly to J2 (with C8 mounted to J2 (all in front to J1 left out)). Could be the LF33 in this circuit too hot (?), because the CPU delivers max 1A - or should it work fine? Greets, rio

Hi, I want to upgrade my MBSEQ in near future. How can I copy my seqv3 data into seqV4? Greets, greets.

Ok, how i had said, i upload a new PCB and a Schematic in attachment. Maybe you have some improvements to that. The signal-to-noise ratio is not so high in contrast to my other audio devices, so if you have some better ideas about that, let me know. CEM3378_handmade3.zip

i will upload a newer CEM PCB and a bit more infos for better result soon.

Hi, i know, thats an old thread but I searching infos. Correct me when I am wrong: Demym wrote: http://www.ucapps.de/mios/j5_dout.pdf --> shows 220 Ohm ! (so demym, your info of 470 is wrong...) Greets, rio

Perfect!

Hello all, I want control 2x CEMs Cutoff and Resonance in 12/4 Resolution. So I have build up 2 AOUT_LC for that case, which are connected to one of my PIC18F452. At least I want write a simple code to control CV1 and CV2 (Cutoff/Reso), but I don't find an little MIOS8 C example to get in. 1. Which source/driver can i use for that pic? 2. How can I initialise the AOUT-Driver, so that it work in AOUT_LC mode? Thx for any help. Greets, rio

Hey communty, I need a tip, how i can adjust a track to fade in or out in an easy way. Is it possible, so that the track starts at 0..127 (e.g. 100%) and as long as it repeats, it should not fade again? (Fade out idea could also be needful.) thanks for any adwise. Greets, rio

thank you for all that information, that was very helpful :) EDIT: last thing, not sure, if it is a bit out of focus: From an electrotechnical view: Is it allowed to feeding an external MIDI-Device with J12 MIDI-OUT PORT from core1, while core1 is also linked to core2 with J11 or could that setup surge core1? Or do I need an extra LTC-Module for that purpose? have nice holidays, greets rio

That is correct. Maybe i don't formulate the question correct: You say it is allowed to stuff the first core with an optocoupler. So, will the first core send data forward to the midi-out port and also to the linked second core (J11) at the same time? So that it works like a router to the linked core, but that i can also get data out of the first core's midi-out? greets, rio

Hi, I have read all about chaining multiple MIDIboxes (via J11) and how I should configure the modules as MIDIbox Link Forwarding and Endpoint. Everything is well documentated here ;). I want connect 2 PIC18F452 together, because the second core needs also some MIDI Messages, which are generated from the first core. Some things should be a little bit clearer for me: Is it allowed to stuff the linked core also with his own optocoupler, so that the linked core can also receive messages from his own MIDI-IN port? Is the first core able to send data through its own MIDI-OUT out as well (so that it routes all events to his own midi-out and to the linked core2 the same time)? I'm afraid, because somewhere in a documents/schematics I have found a note: "Optocoupler NOT stuffed!" for thatt linked core. Thanks and greets, rio

hi, Ah ok, no problem and that shall not give you a lot of trouble ;) My thoughts went more in the direction to have an easier/comfortable alternative for getting FLASH, EEPROM, BANK1..8 (e.g. with a simple click on a button or combobox) instead of input/load special request command in the send-field sysex tool. But the result would be the same. greets, rio

hi peter, yes ok ;). Thanks, e.g. Schaeffer can produce me one of that. greets, rio

hi hawkeye, thanks for info, but i am searching a control surface (frontpanel) not the PCB ;) greets, rio

Hi tk, Very very nice work. Please would you add also a raw "custom sysex library", where i can simple read out from PIC18F452, PIC18F4620, PIC18F4685?: - FLASH (send, receive, load, save) - EEPROM (send, receive, load, save) - BANK 1..8 (32k/64k) (send, receive, load, save) - RAW Receive (receive, save) I know that I can do it all via Request-Commands in SysEx Tool, but that could be a way simpler and it can used for every 8/16bit PIC type. Greets greets, rio

Hello, I feel a bit unsatisfied with my handmade-control surface of my MB-SID. So is there a place/a way where a preprinted control surface can be ordered for the MBSID (with ship-opportunity to germany)? Greets, rio

hi, i tried to change a patch of my synthesizer in another bank with the internal mixermap of my SEQ. In general, changing a bank is easy by sending 2 commands #CC00 (MSB) and #CC32 (LSB) (or in simple way: #CC32 only) with a following #PC command. And here i got a problem. The Mixermap allows program change, but not bank selection. So at time i have to do following workaround: i setup the first bar of the mixermap with the 2 assignable CC1 and CC2 to #CC0 and #CC32 and a following second bar with the program change for same parameters (Port, Channel..). That works fine, but - sadly - it would stole me 8 bars of the 16-bar-mixermap (if i want change all at one time) :pinch:. Is there a better way to setup bank selection for a bar in mixermap? Maybe i could code to send CC2 before PrgChg. greets, rio

To that topic (because i want use C64keyboard and LED outs at one core): is it possible to use also a DOUTX4 in combination of C64Keyboard matrix, so that the first 74HC595 of DOUTX4 will be used of Scan Matrix Driver and all the other digital output shift registers can used for LED outputs? Should be ok, or? greets,rio EDIT: Yes it works, i have not tried that before.

Hello all, is there an example written in C, where i can control LEDs with J5 like the example in http://www.ucapps.de/mios/j5_dout_v1e.zip ? Thank you very much. Greets, rio Edit: ok i found useful informations here: PS: oh wrong topic...that should be in "Mios Programming ( C )"
