These can be had for very little money if your are prepared to wait for delivery from China. http://pages.ebay.com/link/?nav=item.view&alt=web&id=400525336461 Just search "micro USB panel" on eBay and you will find several sellers.

Another reason that it's still relevant is that it provides 5v midi outs where as the MIDI I/O module has 3.3v midi outs. I found some gear won't play nice with a 3.3v midi signal.

These are the same display as the one I have used. http://pages.ebay.com/link/?nav=item.view&alt=web&id=400779379366

Good to know. I'm pleased I didn't buy any. The display I pictured can be found cheap on eBay. I think I paid about £2.80 inc shipping from Hong Kong. The logo printed on the PCB makes it very easy to identify.

I haven't tried those displays but I have has 6 pin SSD1306 SPI displays working with MIOS. Attached is a couple of pictures of a known working 6 pin display. It's not wire up in the photo but I have had this very display working with the MBNG app on a STM32F4 core.

I've been looking at ordering some of these. http://pages.ebay.com/link/?nav=item.view&alt=web&id=371267783096 They should work and can be ordered in bulk from the seller for as little as £2.50 each when you buy multipuls of 10

Im after 1 x 16mm rotary encoder with switch, 20mm D shaft, dented, 24 ppr. Standard Bourns/Alpha/Voti type. I've had all the parts for a Yocto 808 delivered and checked them last night and I'm missing this one part (tempo control). Has anyone got a spare they are willing to sell before I pay a silly amount of postage for one?

How many do you need? I think I have a couple the came from a M Audio oxygen 8 in my "box of parts that I think I'll use some day but probably won't" that you can have for the price of postage.

Yesterday a flashed MIOS 1.9h with a PICkit 3 to four 18F4685 PIC's succesfully. After flashing MIOS I used MIOS a studio to flash the Change ID applications to change the ID's of the chips to 0 - 3. Once I have done this I queried all chips to check they were working fine and I only get a response on all four chips when I query ID 0. I'm expecting each chip to only respond on the ID set by the Change ID application flashed on to it. I have defiantly ran the four different applications, I.e. Change ID 0, Change ID 1, Change ID 2 & Change ID 3. Flashing each chip with a unique Change ID number. I'm pretty sure this behaviour isn't normal and indicates the ID hasn't been changed. Any ideas?

I'm happy to report that these breakout boards work great, you just need to careful with the pin out when connecting the AOUT and DOUT modules. Here is my rough and ready test setup.

Yup, it's a tough call. I love the whole P-Lock thing, it's the main reason I would never part with my MD & OT. After spending 6 months with my MBSEQ it's by far the best sequencer I have ever used, the stuff I can get out of it is amazing! I wish that there was a way to "glue" my Elektron boxes and my MBSEQ together so they could run off the MBSEQ but still have P-Locks.

The MBSEQ V4 clock is as good as they get, even under heavy load. I have a Machinedrum and Octatrack and they sync perfectly to the MBSEQ. The only disadvantage using Elektron boxes with it is that it's hard to choose if you use the internal Elektron sequencer or the MBSEQ to drive the Elektron sound engines ;)

I've just had all the parts for a Yocto 808 delivered and calibrating it requires a scope, so for the time being I only need to work in the analogue domain. Maybe I should save my pennies and get a old secondhand scope off eBay. What features besides at least two channels should I look for?

I'm thinking about buying an oscilloscope and have absolutely no ideal where to start. I've got a budget of upto £300/€400. I'm looking for something that will last me a long time and I won't feel the need to replace in a few years time. Im happy to buy a secondhand scope as I'm sure I'll get more bang for my buck. Has anyone got any suggestions as to models I should be looking at and key features?

I haven't had a chance to look into this further yet but there must be something else causing the optocoupler to fail. As I noted last time I had a look at the sammichSID, the backlight is not working correctly. The screen is very dull. Maybe there is a problem witht the backlight circuit that is causing problems with the optocoupler as the two are right next to each other on the PCB.

It was the opto-coupler again.....I've got it working fine now after replacing it.

Hi Kai, The sammichSID arrived today. I'll try and have a look at it over the weekend.

I have just received a pair of these PCBs in the post http://www.cgs.synth.net/modules/cgs93_trunk.html There absolutely perfect to add 8 x 3.5mm sockets to the AOUT_NG as they have 16 pin headers with a Pinouts that exactly matchs the Pinouts on the AOUT_NG CV output header. It's like they were actually designed for the job. They cost $10 USD and come with a eurorack panel. All you need to add is the 3.5mm sockets and headers. With a bit of fudging they could easily be used for gate outputs connected to a DOUT module. I'm waiting on some 3.5mm sockets arriving in the post and once it's assembled I'll report back.

What you are seeing is normal. Once you have the CS PCB connected the other lines will become active when you start to edit parameters.

The contrast of the display is reduced. I haven't mesured the voltage drop but my instinct tells me it's caused the increase in current drawn by all the extra LEDs on the BLM and TPD. I guess a workaround would be disconnect pin 12 (if I remember correctly) on the DB25 connector that feeds the 5v supply on the transmitter board then power the receiver end somehow. This would not be overly difficulty to achieve. I don't feel this is a show stopper, just a potential issue that should be raised. The other solution would be to use a power supple at the transmitter end that can provide more current which would be far easier though not always practical.

Here is an issue I have came across with the MBHP Line Driver/Receiver and a proposed solution. When using the Line Driver/Reciver with a MBSEQ To connect to one of Illiminator's 16x4 BLM and TPD the contrast of the MBSEQ is reduced. I'm guessing this is caused by the increased current drawn by all the extra LEDs on the BLM and TPD. My proposed solution is to add a jumper that allows the 5v remote supply to be disconnected and a local 5v supply to be connected to the reciver board.

Please Please! After I fitted those MBSEQ windows from you I would never consider a build finished without one. Boobs out! http://midibox.org/forums/uploads/gallery_3551_285_891936.jpg

HI Kai, No problem. Just get in the post and I'll have a look when I get a chance, just don't expect me to be super fast as I've got loads on at the moment. Cheers, Rowan
