Hi, I have a WAVE BLASTER CT1900 with E_mu engine doughterboard. Can be the same or the application is only for DB50? regards Antix

Hi TK, Just payed best regards :thumbsup: Antix

Buondì

YEAH !!! Thanks TK Antix

My SSM2044s are sleeping at Milano custom's offices.

Hi, Usually I use isopropilic or ethilic alchools wiyhout any problems. A good product ( I often use on job ) is Electrolube FRC ( RS code 508-6582 ). It is not very cheap but the sticky traces of solder wire flux will really disappears. Regards Antix

Hi all, Waiting for 18F4685 I had lot of time for give a look to the setup_8580.asm of midiboxsidV2_0-rc37. Seppoman and Nils helped me to understand many things and I am very grateful. I have some questions yet ( seems that the asks are not enough ) 1-In the setup , may I am wrong because my eyes are not the same of years ago, I do not see a define for stereo sid. Is it an "already implemented " feature? 2-Has sense in setup disable unused Shift Registers for save computing power assumed that I will not use a complete control surface? 3-I already realized a MB-LTC for midi message LED , is in the MBSID_V2 the midi-msg led on ShiftReg availability? Thank You for any help Best regards Antix

Hi Seppoman, i have 150 25mills QFP ICs to solder by hand. If You planned to be in Italy let me know so You can give me a little help :D Saluti Antix

Hi, It is not a good thing to short two or more audio source brutally. Better with resistors - more better with resistor and OpAmp ( adder configuration ) in few words a mixer. Regards Antix

OK, It is not a problem for me use toolchain :thumbsup: If I have understood I can connect 5 potentiometers to J5 The wiper to RAn and the extremes to GND/+5V set in the application code "#define DEFAULT_J5_FUNCTION 1" to enable knob function in MBSID V2 menu I can configure and assign the pot and these assigns can control A-OUT too so it is true that every single patch may have different knob function configuration Am I right? If it works like I am imaging it is simply awesome!!! :w00t: I'm only waiting for 18F4685 from supplyer to see SID V2 Thanks and regards

Hi Nils, ASM as I know ( Z80 ASM compiler aged 20 years )isn't so reach of "no properly ASM words". Modern MPU's ASM seems to me more reach so I was wrong but i was convinced that MBSid applications was wrote in C then compiled. Anyway I know Z80 ASM but I have more to learn about new microcontrollers assembler. Thank You for help and regards Antix

Hi Nils, It'me again lookin in the code is there for example ENC_ENTRY 5, 4, MIOS_ENC_MODE_DETENTED2 ; Filter CutOff ENC_ENTRY 5, 6, MIOS_ENC_MODE_DETENTED2 ; Filter Resonance Can I change SR ENC_ENTRY 2, 4, MIOS_ENC_MODE_DETENTED2 ; Filter CutOff ENC_ENTRY 2, 6, MIOS_ENC_MODE_DETENTED2 ; Filter Resonance to readdress and define the SR that controls these parameters in according to my hardware? can I set to "0" the SR that I do not need? Please be patiented but I have no C programming skills so that for You is simple for me may be a wall I'm tryng to learn to use MIOS. Best regards Antix

Hi Nils, Thank You for the very rapid answer. In the Wiki I found this : "Changing DIN pins in mbSID v2" is this the "howTo" that You indicate to me? For the knobs feature I will read with more attention mbSIDV2 manual . Regards Antix

Hi, Is it possible use two or three encoders to control parameters with SID synth? To be clear I'm not interested to a complete ( step C )control surface but I want control only cutoff and resonance. So I would realize a step A surface with a couple of encoders controlling for example VCF parameters or pulse width or external VCF ( SSM2044 with A_OUT ) Is it a realizable stuff ? Thank You and regards

Hi, I used 1/8W resistor on CORE and SID too without any problem Regards Antix

Yes, I will ask. It seems that a lot of aftertouch sensors going to oxidize then a good cleaning may solve the problem. Thank for the link for the manual. Regards Antix

Hi Shuriken, Thank You for the answer but unfortunately I have not a contact problem. Key Contact and dynamic works fine . The problem is the aftertouch. I am start to thinking that maibe useful a D50 schematic to see the zone of aftertouch and make some measures. Effectively if I push very hard on keys a very minimal sound variation exist. At the end in my town is there a Roland service center but I'm sure they will ask me a lot of money....so first I wont to try myself. Regards Antix P.S. the site You indicate is fine

Hi , After years of sleep I powered on my Roland D50 . It works fine...very fine but aftertouch ( from its keyboard ) do not responds. :no: From MIDI aftertouch works normally so it is a keyboard sensors problem. In the net i read that it is a common problem on some Roland products ( JD800,D50 ) and it is caused from resistor in the pressure sensor amplifier that change its value in the years. Is anybody experienced of this or knows a link useful for solving this problem? :console: Best Regards Antix

Hi Monokinetic, It is an idea to evaluate seriously and I never think about it. But You only have to ignore SID refearing on LCD ( only an aesthetic question ) About core 32 I'm hope/waiting for European bulkorder . Smash PCB are very well done . regards antix

Hi Everyone, When I use Eagle for my ( and MIDIBOX PCBs )I ecountered many problems, :frantics: in etching pad and drilling holes because standard holes diameter is too big for a correct manual drilling and copper of pad is too tiny. Effectively they are right for industrial use and metalized holes but creates some problems in home made PCB etching. Tryng to solve this problem i found on the WEB a guy that wrote about a script that solve the problem. :sorcerer: This script create an intermediate layer tha modify drill hole and pads diameters. :) Maibe You already know of this script or use another way but for those like me that dont knew about it I decided to post a link where You can find the file to download: http://ideegeniali.altervista.org/progetti/?p=drill-aid The file is: pshouse-drill-aid-1-5.zip Everyway I hope You found it useful. :console: Best regards

Hi, I'm going to build a Midibox CV but I have some questions. :question: The control volt only drive VCOs or I can drive in real time ( envelope driving ) other parameters like VCF or VCA envelope? I mean is it possible use MBCV to emulate ADSR? It seems to me it is possible in MidiBox SID application. But in stand alone congiguration? Thank You for any answer. Regards Antix

Hi, Very fine job. It looks very professional. I'm interested to the vinyl for inkjet too. Where You found it? regards Antix
