Hi paul You can connect more than one core together. EACH core can have up to 64 pots OR 8 motorfaders. It's all documented in the "MIDIbox Link" section on uCApps. Rowan

Hi Cool idea. I've got plenty of loop and instruments to contribute Rowan

Hi Here's a link I found for cheap 40 x 2 LCD http://www.bgmicro.com/pdf/catalog.pdf Rowan

Hi Nat Caps ( capacitor or condenser, they are the same thing) don't have wattage rarings because they don't consmue real power. The important spec is the voltage rating (as well as the value of capacitane, in Farads). 16V is a conservitive value, but should be considered as minium. Look around is other stores, someone is bound to have one. Remeber allways to buy at least one more than you need. Rowan

Hi Nat use the 10k ohm (this is 10 000 ohms) where as 1 meg ohm is equal to 1 000 000 ohms. It's a very good idea to get use to these prefixes as the world of electronics is full of them. Here is a table of how it works. Perfix M (Mega) =1 000 000 k (kilo) = 1 000 m (milli) = 0.001 u (micro) = 0.000.001 n (nano) = 0.000 000 001 p (pico) = 0.000 000 000 001 i.e 10k ohms = 10 x 1000 =10 000 10M ohm = 1 x1 000 000 = 1 000 000 The bridge recitfier rated at 600v@1.5A will be fine, remember that only 9V-12V is going in to the midibox and 1.5Amps is a pretty large current, therefore it is unlikely your midibox will draw the amount of current.

Hi Thanks for the feed back. Thorsten, Cool. This is just what I needed to know. Rowan

Hi everyone Here's an idea for a feature of MIOS. Having the ability to choose between linear ang log input's on the AIN's. Meaning that you could connect a log pot to the input's and then MIOS scales the sampled voltage to a linear output or vice versa. The math to do this is simple. Is MIOS and the 18F up to the job? I guess this is taking MIOS in to the realms of DSP on a very basic level. Any feed back would be helpful Rowan

Hi Smash TV Thanks for the tip. I have spent many hours trying to do this with no luck. Another trick up my sleeve will be helpful. Any other hints for Eagle would be recived with gratitude How about a VERY basic tutoral with all the basic functions? It could encrouge others to have a go at designing their own boards for pots and buttons (We both know most of the good quailty conponents need to be mounted on PCB's) Thanks once again Rowan

Hi We need as many like minded people in this community as we can get. The more minds involved, the more ideas that will be contributed, the fast this system will develop. We can't rely on TK to do everything for us, One man just dosen't have the time to do so. Therefore as I said above we need more members who are actively envolved in the evolution of the MBHP. Every new member brings with them their own personal expireance and knowledge, which is benifical to us ALL. Anyway back to the topic, A confrence is a great idea. Though I'm not going to be able to afford a ticket to the other side of the world at the rate my MB if chewing through the cash. Much respect and love to ALL midiboxer's Rowan

Hi Good idea Ian. I was thinking about buying some flashing LED, but this sounds like a much cheaper way of achiving the same result. Rowan

Hi Good news! The faders are Alps Just got to tidy up a few details with them. I Should have it all sorted in the next couple of day. As always i'll keep you informed. Rowan ;D ;D ;D

Hi Steve Give this out fit a try, they are in Wellington, New Zealand. www.pmb.co.nz Rowan

Hi Ian and LO (and any other which I'm unaware of) Surplustronics have some VERY nice illuminated buttons at the moment for only $2 each. They are similar to the transport controls that Alex has on his LC clone. RS cat# 339-342 They dont have the coloured caps included but they are avalible from RS for about $1.90 each in Red, Blue, Green, Orange and Opal Only problem is they are quite deep (approx 35mm). They have about 15 left, so get in quick. Cheers Rowan

Hi eBetan, All those buttons are the routing matrix of the desk. These type of controls are standard on all pro desks and also avalible on alot of semi-pro desks. These buttons allow the uses to send analog signals to various places within the desk (i.e. groups/busses which are usualy connected to a Recorder of some discription). Each channel has it's own set. This allows the user to send the signal in one channel to ALL groups (which will usually send to all inputs of the recorder) or you could send ALL channels to one group(therefore one input of the recorder), or any combination there of. For example, you have a Mic/synth connected to channel 1 of you mixer which you want to record to track 8 on your recorder. Simlpy press the button marked 8. this will send the signal to group 8. the output of group 8 is connected to track 8 on the recorder. See the flexiblity that this type of system offers? like I said this type of feature is standard of pro desks (think Neve, SSL etc) so once you understand how this system works you will be able to use ANY pro desk. Rowan

Another one from Auckland, New Zealand. Rowan

Hi pilo Thanks for your reply, I sat down last night for many hours and managed to get some useful results from Egale lite. Rowan

Hi I'm trying to design some simple artwork on Egale lite for 8 pcb mount buttons with a 10 way DIL header to connect to the din's. Unfortunatly I'm struggling with Egale lite, so the whole process is proving to be very unproductive (i.e. I dont have a clue how to use Egale lite). The helpl documentation is proving to be, err very unhelpful. I'm sure if I knew my way round the package it would take no more than 30min to design the artwork Can anyone help? Rowan

Hi all you fader junkiez, Still no word for the supplier. I'll keep you all informed as more info comes to hand. Great minds think alike pay_c. I am thinking on the same lines as you if I have to resort to panasonic motor faders. Every DIY'er konws that anything is possible if you put your mind to it. Rowan

Hi TK Looks great !! One question. Where did the Knobs come from? I'm look for some classy knobs, and yours look great. Rowan

Hi jeroddumas You need to have ALL unsed ain pins to ground, This should stop the ramdom mini events. By doing this you are providing a set voltage level (0V) to the ADC'c on the PIC. If these inputs are left "floating" random fluctuations in voltage caused be atmospheric conditions (noise) will be converted to MIDI data. Rowan

Hi Ian, Back with a vengence, eh see you there Rowan

Hi guys, I talked to Mackie today, I can get P&G's (the ones that are used in the HUI, which I assume age the same as those used in the logic/mackie control). As I expected they are not cheap: $120 NZ each (at the time of writing $1 NZ = $0.58 US). I've been trying a few other contacts. I can get the faders used in the O2R (Alps 100mm) for around $70 NZ each, and the faders used in the O3D (Alps 60mm) for about $30 each. Here is the good news. I have come across some 100mm motor faders which I belive are ALPS (as used in the O2R) for approx $10 NZ each :o :o :o ;D ;D ;D. I've contacted the supplier to get the make, model and numbers available. Let me know if you are interested Rowan

Hi I'm got to order a VU meter for a mackie 8 buss this week, so I will talk the them about getting some P&G's. I'm not expecting them to be cheap, but I think it will less than most other places. If that fails I'll try Mackie US. I work for a company which is one of Mackie's biggest customers, so i'm sure i'll be able to get some kind of deal. I'll keep you posted on this thread when i've got some more info. Rowan

Kia Ora (kiwi's will know what that means, for those that don't, it's hello in Maori) drumwide, I believe that there is no point in having motor faders without being touch sensitive. All this feature does is disingage the fader motor when there is any resistance to them moving (i.e. if you touch the fader while it is moving the motor will stop moving the fader). Without this featuer it is easy to damage the fader. I'm saving for P&G's. I may be able to get them for a resonable price (I deal with the Mackie service department in NZ frequently). Anyone interested? I'll have to follow this one up. Rowan

Hi Good idea. Using a PCB rather than veroboard (board with stips of copper) is a must if you don't have much experince with electronics, one mistake can cause the whole circuit not to work. I'll only use a veroboard if the circuit is simple. When you are building your midibox make sure you take your time. A MIDIbox that does not work is not worth the time you saved. Always tripple check things before you solder, it could save you a lot of heartache in the future. Best of luck Rowan
