Well, I will give Miditrix a try then but I found another thing that most likely destroy the whole sammichSID thing for me... :cry: ... so far I did all testing with a simple 44khz Cubase project but all my real project are 48 khz... and when I start the Editor it resets 48khz to 44khz ?! :sad: :hmm: :geek: :nuke: I don't understand why it triggers the sampling rate at all... Using the laste Motu 424 drivers ...

I don' have another OS at the moment and I can't get the editor to work properly. I did not try miditrix but ain't that the same as MidiOX (virtual midi ports) ? MidiOX did not change anything. Is the editor actually still maintained?

Yes, comparable to bulbs.

I think the PSU is fine. I use 8580 chips and I they emit the most noise of all my synths. I have no problem with it tho. In fact I own a noise sample collection. :-)

http://www.conrad.de/ce/de/product/518322/STECKERNETZGERAeT-PA-1000S-LED This is the only available non-switchmode psu that I know. As you probably know, these old-school psus are/will be forbidden in Germany and Europe. I have to add tho, that mine only delivers 11.51V.

Yes you can unless we wan't to turn this thread into a general desoldering thread :-)

I investigated further and found out that if I change the Cutoff Frequency and then change another parameter, the midi connection gets fucked up. It is not the sammichSID. The Sammich just does not get any notes anymore until I change another parameter again. The severe bug occurs with: Win7 64bit Motu Midi Express 128 I tried the editor with the ESI Romeo Midi Interface which uses standard midi driver and the editor does not work at all with it. I also tried to connect MidiOX but it does not change anything. Big let down as I intented to remote control the Sammich -.- Any idea what I can do?

I have a problem / bug with this editor: Editing seems to be working fine until I change the Cutoff Frequency. After that, whenever I edit a parameter, the sound mutes. If I then change the Cutoff again, the sound plays. If I then edit another parameter, the sound mutes again. So basically, I need to always change the Cutoff after every little editing, to be able to hear the sound. Using the hardware only works. Any idea how to solve this problem?

Hello, you could try to put caps into JBP to override the bridge rectifier. Which voltages do you have then? And which voltages do you have between GND and 5V ? I have a non-switchmode adapter 12V but it only outputs 11.51. I currently run the Sammich sucessfully with the method described abobe. With bridge rectifier I have 8.5 at 9V , maybe exactly the half missing V. A general tip that helped ME, is to get the pcb charts and make sure everything works. Doing only the voltage tests described in the buildnig manula did not help in a few occasions. http://www.midibox.org/dokuwiki/lib/exe/fetch.php?hash=a55f1b&media=http%3A%2F%2Fwww.mb6582.org%2FsammichSID%2FsammichSID_Base_PCB.pdf http://www.midibox.org/dokuwiki/lib/exe/fetch.php?hash=b46a35&media=http%3A%2F%2Fwww.mb6582.org%2FsammichSID%2FsammichSID_CS_PCB.pdf I hope I could help a bit but the more experienced guys will surely do so :=)

Wow, that quick chip stuff seems to be very good. In this video, they guy smoothly heats up 4 sides of a chip, 1 after 1 and then simply takes the chip away. So the solder seems to be very hot and liquid for a long time. Thanks for the hint. As for my problem, I finally removed the resistor after cutting it into pieces and then removing it pin by pin. Afterwards I placed the PCB so I could heat the joints from one side and remove the solder with a solder-sucker from the other side. Like Wilbe described. So far, the Sammich seems to work well but I gotta check it's behaviour more in detail over the weekend. I actually found a problem, but it seems to be java-editor based.

*Sigh* I have a question again. I bought a stabilized 12V power supply (LINK) and plugged it in, without any electronic consumer behind it, and measured the Voltage. The result was 11,51V. I also have this 11.51 Voltage at certain points when I connect my not yet ready Sammich to it. My questions are: - Is the power supply malfunctioning? - Could 11.51V be enough for the sammichSID if I only use 8580 Chips? :question: Thanks

Thanks guys for your support. I ordered a new resistor, they are really cheap. To a noob like me it was quite surprising HOW cheap most standard electronic pieces are. The most striking tip that you guys gave me, is that, if you want to desolder something, it might be a good idea, to add even more solder first. I will remember that.

ok , nevermind, there was actually already a question like that and it looks like i have to cut this thing out and order a new one. God damn.

FFS. This just had to happen: I put in one bus resistor with the wrong alignment. Position RN1. I am trying to desolder it since over 2 hours but I have no chance. I have a soldering sucker and desoldering braid and I did remove some solder. However, the resistor is still mounted to the pcb rock solid. I tried to lever it out but I did not use brute force because I can damage the pcb contacts I think. I know the net is full of desoldering tips but I feel helpless at the moment. Any idea, maybe a RN1-specific one? :cry:

I have to admit ... it was a bad soldering joint of the bridge rectifier and to be honest I even looked with a magnifying glass before starting the thread :geek:

Well, Noobi-Me did not expect to make the Samich run instantly but the first 5V was total failsauce :geek: When I configured the Sammich for 8580 SIDs I got 0V everywhere except between GND and the 12V pin of Header JP where I had 0,3V. :cat: But Noobi-Me had an idea :sorcerer: and changed the setup to powering 6851 Sids directly from the power supply. Which means bypassing the bridge rectifier and voila: 5V everywhere (where supposed to). However, I do not know how to proceed. :question: Where to measure or what to do. All I can imagine is resoldering the bridge rectifier. It is aligend corectly - flat to flat. Maybe it's broken? :shocked: If anyone has an idea, thanks! :wacko:

Thanks for your reply Rosch. My Multimeter has sound, and yes, its not the normal sound. It's just a crippled sound for a second.

Excuse my noob question but I assume that there should be absolutely no connection btw. GND and 5V, is that correct? Because I got one :geek: additional information: - the pcb is OK, I tested this right away, as suggested by the Wilbas manual - so far, I did not find any soldering shorts ( which ofc doesnt mean that there are none, gotta check again tomorrow) - I found the connection with my multimeter, using the continuty/diode testing method The connection is not like a complete short, the multimeter says: 753 - I made occasional tests between the different soldering stages. I believe that the connection came after mounting the voltage regulators, bridge rectifier, 2200 uF Capacitator and the in out connections on the rear - I think I mounted the voltage regulator nicely and I did not use conductive heatsinking

Hi Erics, danke für den Input :)

Is the Sammich still available? I tried to solder a simple training pcb with some LEDs today and failed so miserably that I am interested in this.

Ja, OK, dachte mir schon, dass es nicht so kritisch ist. Danke für die Antwort :) Beim Netzkabel habe ich übrigens nur die Kabelenden verzinnt und dann im Stecker verschraubt. Der cut war 40 cm vor dem Ende, da habe ich das ganze Kabel gekürzt :)

Ich kann zur eigentlichen Frage leider nichts beitragen. Aber wenn ich es richtig raushöre, möchtest Du vielleicht auch Plugins einfach per Hardware bedienen können. Dazu möchte ich empfehlen einen Blick auf die Software Novation Automap zu werfen.

Hallo, ich bins, der Drehpotiprofi und ich habe nochmal eine kleine Frage. Und zwar habe ich mittlerweile meinen Lötkolben und heute habe ich ein Kabel gelötet, dass ich letztes Jahr aus Versehen bei Garten-arbeiten durchsägt habe (leider hing die Säge dran und ging dann aus). :sorcerer: Wie auch immer ,meine Frage lautet, ob man Lötkolben, vor dem ausschalten nochmal sauber macht oder einfach Restzinn drauf läßt. Wie ich ja gelernt habe, soll man bei LötPAUSEN Zinn drauflassen!

I am also interested in heatsinks. How high can heatsinks be within the Sammich? (Mine is not here yet)

Jo, Ok, danke :-)
