Yes, they work fine when this line is not added, one detent per increment, and performance is good, and they work properly when I modify the hardware, so I thought that I made an error in the conkinde that was causing poor performance. It is no big deal to correct the hardware. I will just do that. Thanks~

I am trying to do the same thing, I've added the line so that it looks like this: USER_ENC_NotifyChange comf MIOS_PARAMETER2, F ; inverse incrementer movf SID_MIDI_DEVICE, W ; exit if device ID != 0x00 skpz return and the encoders work in the opposite direction, but now I have to turn past several detents to increase by one increment. My encoders in general behave erratically when this line is added. Can you spot my mistake? I added it by copy/past in a text editor the main.inc file. Thanks for your help, looking forward to learning more about this since it's the first time I've done anything other than change din and dout assignments.

IGI, thanks very much for your upload of the swinsid pcb, I etched on last week. I still need to drill holes and order components for it. Can you tell me where I might find the DAC in USA and perhaps a full parts list in english?

Hey, Check out TK's schematic for the optimized c64 psu, it's in the walkthrough. Basically you use this circuit but remove the portion of the circuit that combines 9 + 5v and rectifies to 14vdc (because the hd psu already has 12v) PM me for more info

If you do a search of the forum you'll turn up several threads regarding power supply options for midibox sid. My C64 power brick died on me recently so I used the power supply from a broken external hard drive enclosure that delivers 5v and 12v, each line is 2amps. I also added fuses and used 2200uf electrolytic capacitors and a 220nf and 330nf polyfilm (for 5 and 12v in that order) to filter any noise out. This works great for me it gives me very stable reliable power and I cannot hear a difference between this and the optimized c64 psu.

Wow, That's creepy.Do you have some kind of analysis software? Or is this just a gut feeling?

You should work with peter lindener on that one, he's another guy around here who wants to make midibox and arduino talk to eachother. What is the goal? to run mios on arduino? or to use an arduino to add extra functionality to a midibox?

He's talking about the sx-64 it was a portable commodore with integrated display and disk drive, the granfather of the laptop.

Sorry for being rude Peter. It was late, I read several of your post in a row because you made several most recent posts in different sections of the forum yesterday, and your bragging about coding skills made me irritated and perhaps jealous since I am lacking in that area. I was actually quite serious about helping you with assembly in exchange for some software help. I will PM you shortly.

Since you joined the forum you have proposed to make midibox more like arduino which is inferior in many ways. You also complain that there is no pre-assembled arduino style dev board to purchase, you also ask for information on programming for MIOS32 then when the creator of the project takes time to personally link to some of that information, you reply with the links he "should have" given you and complain that the documentation or the site structure is not logical enough for a newbie, when clearly you were able to find it on your own, and you keep jumping back and forth between "I'm such an awesome programmer, I just know I can make apps for MIOS in my sleep" to "It needs to be more newbie friendly" to "I could totally revolutionize the whole platform and the website if only someone would build me a core32" to "I've got a really original idea, let me sell the hard work of this community" to "Gee, you guys are overly zealous and you're not a very welcoming community" Come on guy, you have all these ideas which you think are huge, which basically consist of taking the arduino business model and applying it to midibox, and you claim to write awesome apps in your sleep, and you want to use that talent for midibox apps, and you've got plenty of energy to write lengthy posts about your ideas but you can't be bothered to do what's currently necessary to acquire the hardware that these ideas would hypothetically run on..... Just keep an eye on the fleamarket, ocassionaly someone will sell an assembled core32 because they have given up or need cash, or whatever, there was a guy just last week offering to sell an assembled and tested core32, sorry, you've just missed it. I'll make you a sweet deal. I can't be bothered to hack the ableton live API and I'd like a midibox app that can control every parameter and receive every imaginable type of feedback from ableton, so you go ahead and develop that app for me and I'll build me and you a core32 and everybody wins! I can assemble a core kit in my sleep between wet dreams, oh BTW, "you're doing it wrong" PM me if you wanna trade efforts, that's how we do it around here.

You can either take it to a screenprinter and have them do it for you, it will probably cost about $25.00 to burn the screen, and $1.00 per print per color, or you can just buy a screen, squeegee and ink at a craft store and do it yourself. You can build a single color press with a wooden table and hinges from the hardware store. This would be great because you can also make t-shirts for you band with this setup. "Plastisol" works great on cotton or 50/50 tees and it will also work on the album jackets. If you choose to have a professional do it, you could save money by using the same design for your cover and the shirts and having them do it all at once. You can find all kinds of screenprinting tutorials online. It's a lot of fun and a good skill to learn which will be useful for promoting a band, posters, t-shirts, etc.... BTW, if you establish a good relationship with a local printer, they'd probably be happy to expose some PCB's on photoresist copperclad board for you when needed. The exposure units they use for photoemulsion in the screen-making process are perfect for PCB's

I have The Postal Service "Give Up" on vinyl, it doesn't sound much different, it the record is mastered and cut properly it should sound very close to the digital master. If the original recording was done on tape, and then mastered to tape, then cut to vinyl you could argue that the analogue signal path was maintained from start to finish and never compressed.... Consider cutting a 7" single, the cost should be about 35% less and you can just include a digital download link for the rest of the album. Also, just get the plain white jackets and silkscreen the artwork yourself, it will be much cheaper and way cooler DIY punk style!

It must be your wiring. Are you using a single stereo pot for feedback, or two mono pots? Please photograph the connection of the wires on the jacks, pots, and sid modules specific to the feedback mod and repost so we can verify.

How do you increase the voltage sent from DOUT?

wow, is that 9v battery almost dead? or is that really big resistor? and what's the point of testing LED with wrong voltage?

I can print them on adhesive backed vinyl and cad-cut the holes when you're ready

Hello, I've built a small controller to launch clips and such, I wanted to know if it is possible to reassign pins for my buttons and led's (not rings, just single) or do I have to stick to a default wiring? I looked through the setup.asm, but I only see that entire registers (groups of 8) are assignable, not individual pins. Would I be better off using another app? I have buttons and encoders in this project.

Most people only charge for parts, the value of labor cannot be defined, I only make $10.00 per hour at my day job, but you may make $35.00 an hour, does that mean a core that took me two hours to build is worth $20.00 + parts, while your core is worth $70.00 + Parts? See the problem here?

OK, This may sound like a silly question, but how can I invert the voltage to get -5 for this chip? My power supply has only +5 I'm thinking it requires an op amp, and I have a few, I'm just wondering what's the best way?

A worthy candidate for MBSID? I already built the c64 optimized PSU, but always looking for a modern solution: http://www.paia.com/proddetail.asp?prod=K114&cat=50

Look into driving it from J5, I know you can control leds from it.

Hey guys, I've been looking at some of the pre-made 8x8 LED matrix available, and I think I'd like to use one of these for a clean, simple installation. A few questions: 1. is it necessary to use transistors? Or can I simply hook them up as shown in the default DOUT wiring schematic? (MBSID) What is the advantage of using transistors? 2. I have seen computer software for some simple LED matrix projects that allows you to program animations and simple graphics to display on an 8x8 matrix, would it be possible to play these on the midibox somehow? I know it's possible, but would it be realistic for someone who has no assembly language experience? 3. As a workaround, I have considered getting a bi-color matrix and hooking the second color up to a dedicated control board that would allow me to play little animations and graphics when I'm not using it for midibox, since both colors share a pin (either cathode or anode) would this cause any damage to my DOUT? 4. Check out some links that got me inspired: http://www.youtube.com/watch?v=JqH4_tATKhc I look forward to hearing your thoughts on this!

I'm not sure that I understand how that would work. Is this something that would be used to combine control voltages from external sources?

It would be fantastic if you could forward to those three parameters, I think "pitchbend" would be very useful if a user wanted to build a pitch bend wheel or joystick into the control surface. I understand that it would not make much sense to do alternate mappings since the "assign" layer is optimized for the five parameters on screen. I also understand that you must be very busy, so if I never see this feature I will understand. Have you had any other ideas about functions these pins could be used for in the future?

OK, I built as much of a control surface as possible with only 3 shift registers (One of my shift registers is bad, I confirmed this by moving it sround and the problem followed the bad IC) anyways I have 5 menu select buttons (4x20 LCD) page up, page down, shift, inc, dec, execute (main menu button) menu encoder, 5 OSC encoders, and the "ctrl" button that toggles between "knob" "misc" and "osc" encoder layers. So I have another question about analog pots while I'm waiting for another shift register: If I hook up the Env "ctrl" button, can I use the analog pots to control the env layer? Or am I only able to control the "assign" layer with analog pots? Also, I got a really nice pitchbend/mod joystick from an old korg keyboard that got broken by UPS. It has one 10k pot on each axis. I would like to hook this up to J5 also. Any chance we can make use of the three unused pins on J5 soon? Like, it says in the walk through "for future features" and I'm sure that was written in the distant past..... I know you're a busy guy TK, but it would be really awesome to be able to use those other 3 pins. I would hook up the joystick, and an analog ribbon controller! If not I'll just get a toggle switch so I can choose between the joystick or the first two pots, but it would be so cool to be able to control unigue parameters with the Joy instead of the same stuff I can do with two of my pots!
