Synthy

I am working on a project to get the CEM3396 alive. I have programmed a Arduino to output 2 midi controlled, freq modulated, independent square wave oscillators. I also have programmed a LFO with saw+, saw-,sin,tri,square and S&H. I also have programmed a 6 part envelope generator. To envelope 6 voices at 1 time, so you need at least 2 of them. I also have programmed a midi master module to send seperate midi to the specific voice. I am working on a voice PCB with the filter options like the xpander from Oberheim. If i am ready to let you hear or see something, i will post it.

I am searching for 58 button caps for MB SEQ V4 tactile switches (12x12). If someone has these in his drawer, please contact me. Regards, Pim.

I suggest to close thuis thread to avond this endless quarrrel. Open a new one heen the boards are ready to order.

Hi Lisa, Did you order yet or could you put me on the list? Regards, Pim.

Hi, Connections are mostly the same on every type of display. Try this: http://www.ebay.com/itm/ZYSCOM-LCD-Display-HD44780-4x20-chr-20x4-BLUE-STN-NEGATIVE-Backlight-/221830149300 . The datasheet is there. Regards, Pim.

I am looking for a PCB MBSeq V4 CS. If you have one left, i want to buy itfrom you.

I have made an Arduino shield powered by the YM2151. This is a 8 voice FM synth witch is also in the DX21 and DX100. I have ordered 10 PCB's so if anyone is interested, i sell them for 25 euro's ex. shipping. It comes with a sketch to control it completely through Midi. I have also made a panel in CTRLR to control all of the shield. Demontsration at: www.youtube.com/embed/uvQk5IbCYwE

I would like to have a standard message in my lcd. When a enc is changed, the value of the enc should be visible in the lcd. After a few seconds, the standard message must be replaced. Is this possible? In the standard message are the values of a few enc's.

Do you still have the st32f4 baseboard with midi out expansion. As i am interested. Pim.

I had forgotten to change the rb2 and 3 back to re1 and 2. Now i did and the sound is good, but the d0 to d4 lines are still high with the interconnection test. So this test is not good for the 18f4685. Problem solved.

i have now tested with 18f452 and its sounding great. When i put in the 18f4685, there is no sound at all.

I am sorry i did not respond to you earlier, but i missed your post. It is sold. Best regards, Pim.

I am testing everything, but what i want is the sammichFM software.

I did consider that, but i used the same hex file for the 4685 and 4620. I consider also that this file may not completly exchangable but i got some sound from my opl board.

Thanks for your reply. When i have nothing connected, the outputs of d0 .. d3 are high. I use mios v1-9g with bootloader v1.2b. I have built another core with only nessesary connections and it stays the same. Best regards, Pim.

I have tested all connections and pcb's, but my opl card will not produce any sound. I have tested with interconnection test and the result was that on d0 to d3 have continous 5v. They are not affected by the interconnection test. I have put in a 4620 with the mios from 4620 and with the sammichFM software. Now i can hear sound when i touch the keys on my keyboard. It is not correct, but i can hear sound. I think my OPL card is ok. What do i do wrong?

The sale is on again, because the buyer did not want it afterall.

I am selling my MBSEQ V4. A few pictures are in the gallery. The price is 400 euro.

Thanks Thorsten.

I have problems with datawheel combining with up/down buttons. If i look at the file MBSEC_HV.V4 it seems that up/down buttons are already implemented and connected parallel with the datawheel. This is not working. I have to press two buttons at ones to get any response. What is going wrong?

You were quite right Shuriken, in Notepad++ there is between every line an extra line. Thanks a lot.

The only empty line was the last line so i only was able to remove that one and it did not have any result.

Hi Shuriken, i have removed the empty line at the end, but it is not good. I still get the message Error reading Hex file. I have downloaded it from the IIC page. Or if someone else knows what to do please reply.

I want to burn the 16f88 with my PicKit2 burner, but it will not read the hex file. I have found some other files from TK and they also could not be read. What seems to be the problem? Is the format not right?
