I plug two roland pk-5a to have 1 octave above the other one but the problem is I can't play in the BASS MODE or MONO MODE with the HOLD function on and stop the note I play on one unit when i play a note on the other unit. The question is: can i fix something on the pk-5a or i have to made a special midi box to go in between the two pk-5a to send a midi message like midi off or cancel note or something like that. Thank

1. Check the power cable and ensure it is securely connected to both the amp and the power outlet. 2. Check the fuse and replace it if needed. 3. Check the power switch and ensure it is in the correct position. 4. Check the battery (if applicable) and replace it if needed. 5. If the amp is still not turning on, contact Roland customer service for further assistance.

Hi, With my sound engineers hat on I would use a small PA. mixer, amp and speakers!!!!
For quality you need a full, flat frequency range system with good headroom.
I assume this is for your own listening, when using an acoustic kit?
There are one box solutions.

1. Drum amps. Like a monitor wedge with an amp, Roland do a PM-10, Various other makes are available.
2. General purpose powered wedge.
3. Keyboard Amp, these are full range and available in various sizes.
4. Bass amp with high frequency driver (tweeter), not the best but will have good bottom end.
5. Powered or active speaker, much like a powered wedge, but a different shape, needs an input volume control.

All these systems need to have large bass units, 10 inch minimum, and will be in mono. Two will give you stereo,
How loud depends primarily on the sensitivity of the speaker. But manufactures insist on selling things by power. Worth looking this up.
At a couple of feet away, 20 watts should do it, with high sensitivity speakers, more likely you find most things as above start at about 70 Watts.
Good luck, I hope I have widened you choices a bit.
All the best, Chris the Fader.

It sounds like the piano is in mono setting. One note at a time can be played. Find out how to set it at poly mode, allowing multiple notes to be played at the same time.

A very slight delay would be normal as it takes the pedal electronics time to acquire and creae the second harmonic. The ear is sensitive to about 1/1000 second. You haven't said how much delay it is causing... If it is over 1/20 of a second there is a problem.

Yes the output jack socket can be used either to:

• plug in a set of headphones for personal listening / practice
• to connect to an amplifier.

The zoom pedals use either a mono or (tip and sleeve) or stereo (tip, ring. sleeve) 1/4 inch jackplug - i.e a standard guitar lead.
You should plug it into a line-level or high impedance socket on your amp. With the pedal in play mode you can adjust the output level (gain) to match the input requirements of your amp by rotating the 'Value' knob (top right)

Read page 135 regarding the note range settings. Look also for keyboard split information. You may have the keyboard set to NOT play notes in the top octaves for the particular voice you are using.

usually If a certain note doesnot play the note before it is not seating correctly. Check all pads that they are sealing behind the bad notes, also make sure the octive key is sealing.

In Casio Chord mode, the bottom keys up to the second F plays Bass Chords. The Keyboard is just putting the keys you play back into bass when you get up that high. If you read along the plastic edge above where they keys come out of the keyboard, it shows you where the Chord keys end and the Keyboard begins. If you want use of all the Octaves, slide the power switch to the first setting (normal).
