Hi, i need to know the exact power plug so i dont have to run the pedal on battery power.i know i need a 9v power supply but i dont know the size of the jack that goes into pedal..many thanxs..


Unfortunately, battery jacks and plugs similar to the type you're describing do not have any real standardization - unlike the outlets and plugs in homes and businesses have.

You best bet is to either bring the plug / jack to a shop to match it or contact the instrument's manufacturer to obtain the connector specs for physical dimensions

Be sure to obtain the power requirements in either watts or amps so that you can obtain a power source capable of delivering what you need without overheating during longer periods of use. Adding 25% to 50% more amps or watts to the minimum required should provide years of trouble free service. Example: 9VDC at 50 watts should be supplied by a 9VDC 62 watts or even 75 watts; or in the case of a rating of 9VDC at 6 amps should be supplied by a 9VDC at 7.5 amps or even 9 amps. With DC powered devices, make sure you observe proper polarity! Good luck!

RC looper and DR880 syncing.


RC-50 & DR-880 Setup
Rather than using the RC-50 to change patches on the DR-880, I have connected an FS-6 footswitch to both the RC-50 & DR-880. This gives me control of both units, I can select up & down through the patches easily.
Use a dual TRS connector and 2 stereo "y" cables connected to ports 1,2 & 3.4 on both units.
Once connected, you will need to assign the control function for each control port. I assigned Patch Decrease to CLT 1,2 & Patch Increase to CLT 3,4 on both units.
I then connected a MIDI cable from the RC--u control of start/stop & tempo via the RC-50 footswitches.

Goodmorning, I'll try to explain the problem: when I listen to the files (MIDI and MP3) directly with Cakewalk sd-50 using the USB Key the playback is correct. When I listen to the files playing them...


You have to make sure that the clockspeed of the program that you use to play the files back with matches the clockspeed of the program that created them. I might be wrong about that. Here is a good resource:http://forum.recordingreview.com/f18/midi-troubleshooting-101-a-5208/ You will have to join to access but its free and the Killer Home Recording setting up is also free from the site and is full of good info.

What kind of lithium battery does the D 50 take?


The schematics I found for the Juno D do not show any battery.

I damaged my boss BE 50 by using the wrong polarity. now it only works on batteries. what can I do.


You are probably fortunate that more damage was not done.

Open the unit and you will likely find a protective diode at the input and either a fuse or that a circuit trace has been blown. Replace whatever is not conducting the power from the power jack to the rest of the circuitry. The diode is probably OK as usually the battery power is across it when the battery is used.

New speakers required?


Possibly, however if output from ME50 is to "hot", that might be some of the culprit (overdriving input)

Beggining of loop missing on FIRST playback only, on Boss RC-50.


Ok, solved this problem by visiting roland U.S. site as the help offered in this country is useless. The instructions given by email would not have worked even after the update was installed. Luckily, there are instructions that come with the download. If you have same problem as me go to http://www.rolandus.com/products/productdetails.php?ProductId=772&tab=downloads&skip=true

and update the opperating system on the RC-50 to RC-50 System Update Version 1.01.

Then hold loop sync and phrase 2 button (think it was phrase 2) to change it to sound priority mode. Then it will play back correctly what you recorded on the first loop, rather than missing the first beat.

Am v.happy I have found this, as after much searching I can't find any other loopers out there that offer 3 seperate loop tracks and the ability to switch between them effectively. Plus, it's a very convenient size, better than a load of rackmounted stuff to haul around.

However.....

Another problem..

When hitting the reverse switch ( I assigned both external footswitch and the onboard Tempo pedal to reverse) the change is not instanteaneous. There is a second or so delay before it plays in reverse. Not a problem for most, I suppose, but I have a piece that switches rythmicaly between playing forward and reverse which means hitting a pedal in time and reverse/forwards changing immediately. I think they could do with another software update to solve this. Now I have to keep room in my enormous pedal board for the old rc-20, as that does the reverse as it should - when you hit the flippin switch!
