Yamaha Electronic Piano- certain notes malfunctioning
Either the first or second closure matrix line for the "A" keys is bad.
This may be a cracked or shorted circuit board.
A bank of diodes is used to prevent sneak electrical path if more than one octave has notes pressed.
First thing is to clean ALL the key contact areas and the conductive rubber pills with 99% isoprophyl alcohol.
This involves dis-assembly of the key area. If you are not competent in electronics, best left to a pro shop.
The keys are scanned in a matrix, two contacts per key and all the individual notes are in common (all the "A;s", "B's"...) And each octave is strobed for the first set of contacts and then for the second set of contacts. an the whole octave is read in parallel.
The reason for two contacts is one closes first and then the other as a key is lowered. The time between these is measured and is the note VELOCITY which for a piano controls the loadness of the note. IF ONE of the two fail, the loudness will vary as yours does.
The middle E key seems to come on at full volume
The contact under that key in the contact membrane is probably needing to be cleaned or replaced. It can be done by you but requires disassembly of the keyboard and removal of the key and adjacent keys to take the contact out. Rub the contact and the place on the circuit board where it makes contact with a pencil eraser and clean the residue off with isopropyl and a qtip. The membrane comes in strips and is replaceable if you can still get the p[arts. You might be better off to consider having it serviced. Hope this helps.
Roland 3000 Digital Piano 88-Key Full-size weighted keyboard
It's not really for the faint of heart, but generally this is caused by gunk getting into the key circutry. Underlying the 3000's keyboard is a silicone pad with 2 contacts on it, the measurement between each being hit is the issue usually but yours just sounds like there's something in there causing a physical or contact obstruction.
What you really want to do is to remove the keys and clean everything but this isn't easy... You could try using 99% alcohol (from a pharmacy) to clean inside it which may well help you.
There's a good thread on a similar issue at:
http://www.electronicspoint.com/roland-hp-3000s-digital-piano-dodgy-note-t18946.html
Which may help you work out how to do the disassembly if you are brave, but I would start with pouring some alcohol in and poking it and hoping for the best 1st. It sounds crude, but it works amazingly well with some things.
Will a midi interface allow me to play downloaded music on a yamaha clainova 305
Yes, with some preparation. The music will have to be in a standard MIDI file format or a format that results in standard MIDI over USB output when "played" by computer software or an external sequencer. Within the software you will probably need to create a new "instrument" if there is not already a template for the CVP 305, otherwise the tracks and sub channels in the MIDI file will be patched to GM, probably not what you want to hear.

What is the best way to reprogram a Yamaha WX5 Ewi
Reprogramming a Yamaha WX5 Electronic Wind Instrument (EWI) typically involves adjusting settings, assigning functions to different keys, or customizing parameters to suit your preferences. Here's a general guide on how you might reprogram a Yamaha WX5:
- Access the Menu:
- Turn on your Yamaha WX5.
- Navigate through the menu options using the buttons or controls on the instrument. Refer to your WX5's user manual for specific instructions on accessing the menu.
- Select Parameter to Edit:
- Once in the menu, find the parameter you want to edit. This could include things like breath sensitivity, pitch bend range, or assigned MIDI channels.
- Adjust Parameters:
- Use the controls provided on the WX5 to adjust the parameters. This might involve turning knobs, pressing buttons, or using a combination of controls.
- Save Changes:
- After making your adjustments, make sure to save your changes. The WX5 typically has a save or store function within the menu. Confirm the changes and save them to the instrument's memory.
- Refer to the Manual:
- Consult the user manual for your specific Yamaha WX5 model. The manual will provide detailed information on navigating menus, adjusting parameters, and saving changes.
- Connect to a Computer:
- Some advanced customization may require connecting your WX5 to a computer using MIDI. You can use Yamaha's dedicated software, if available, to reprogram certain parameters.
- Use External Sound Modules:
- If you're using external sound modules or synthesizers, some customization may need to be done on those devices as well. Refer to the manuals for your MIDI equipment to ensure compatibility and proper configuration.
- Explore Advanced Settings:
- Depending on your proficiency and the complexity of your WX5 model, you might explore more advanced settings like custom MIDI mapping or adjusting sensitivity curves.
Remember to approach reprogramming with caution, especially if you are not familiar with all the settings. Make note of the default settings before making changes, so you can revert to them if needed.
Always refer to the user manual specific to your Yamaha WX5 model for accurate and detailed instructions on reprogramming and customization. If you're unsure or uncomfortable with the process, consider seeking assistance from Yamaha support or experienced professionals in electronic wind instruments.
