Open the unit and see if it has a battery that holds the settings. Check the voltage... it should be around 3 volts. If less than 2.5 volts replace it.

Verify the INTERNAL regulated power supply as the external you verified with new unit. The external is likely regulated within the D4 and either due to an overload or bad regulator may be below the voltage to run the processor. It is likely 5 volts and anything over 4.85 would be acceptable.

    I Have the exact same problem with my Alesis d4...! The solution you suggest is very technical...To much for me, who could do that for me ?

  • bbobboss Oct 19, 2010

    Hi man, While I was reading about trouble about the Alesis d4... you seems to know a lot about it. Do you think I should ship my module from Montreal Canada to Alesis USA for them to repair ?

    Or just find someone like you near Montreal ?

    Both, find a competent electronic technician and do show him my suggestions for starting troubleshooting. Often factory repairs can take a long time and sometimes they just send a refurbed unit that might be older than your own. I understand my suggestions are technical which is what you get from an electrical engineer, however they will be understood by someone qualified to work on the units.

Anybody ever figure out the Alesis DM10 module blank screen with some led lights on?

Try a reset before going to assistance:
There are two ways to reset the DM10:
To fully restore the module to original factory settings, hold the EXIT and STORE buttons while powering on the module.
To reset only the kits, sequences, or trigger settings:
  1. Press UTILITY to enter the main Utility Menu.
  2. Press SYS (F4) to access the Accompaniment Settings.
  3. Press INIT (F2) to access the reinitialization page.
  4. Use CURSOR UP/DOWN to move through the following menu items:
    • All Kits: All of the module's kits and their settings will return to factory default
    • All Sequences: All of the module's sequences and their settings will return to factory default
    • All Trigger Settings: All of the module's trigger settings will return to factory default
  5. Highlight the option you would like to reset, then press EXEC (F4).
  6. A window will appear asking you to confirm your choice. To confirm and reinitialize the selected settings, press YES (F1). To Cancel, press CANCEL (F2 or F2).

I have a DM5 18 bit drum module. It is a while since it was last used and I can't find the mains adapter. I bought a new one and have it set at 9V. The unit switches on but it is very dim and I...

You CANNOT use one of those universal adapters, period. The DM5 Alesis takes an AC output adapter. You need 9 VAC at 830ma or more. AC output adapters are hard to find and you are not the first to try a universal and find that they don't work! Here is one of MANY sources on Ebay:

It appears that you have to select a "Kit" of drums when using the external triggers. It appears that the volume level for the kit and that for each voice MAY all have to be set, especially after new firmware download. Read manual about KIT volume level and selecting voice and volume level for those. Manual is NOT very clear about these things and you have to try them as this is where the probllem is.

Only distortion..

Check your power adapter. This unit REQUIRES a 9 volt AC adapter, NOT a DC one... It MAY appear to operate on DC BUT it can't generate the +/- voltages internally for sound generation with a DC adapter. This is a common problem as people try to run these on a DC adapter.

I'm trying to use the pads of my Yamaha DTXplorer drum kit as triggers for the sounds stored on my Alesis SR-18 drum machine. I have seen that Alesis markets a trigger module of their own which they...

you need to determine what midi note the DTXplorer is using for the snare, kick and 3rd tom, and set the SR-18 accordingly, or vica-versa. the midi notes for each instrument has to be the same.

if you cannot change the midi note in either unit to make them correspond, you can download a "midi mapper" program (i think e-drum might be one), there is freeware available if you search CNet. with a midi mapper program, you would have to get a midi/usb adapter for your computer and rouite the midi signal through a computer. midi mapping software allows you to change the midi note, when the hardware itself is incapable of doing so.

Blank display no functions power ok

Not sure what you mean by "power OK",

If you have checked that the logic circuits are getting a clean 5 volts DC THEN the power is OK. This requires an oscilloscope AND a voltmeter.

USUALLY when a display shows characters like that it means the processor hasn't initialized the display. Most common problem is too low power supply that doesn't permit the processor to come out of reset.

Bad filter caps can cause the 5 volts to dip below 4.6 volts which would be minimum to operate. A voltmeter might still register near 5 volts but a scope will show the voltage dips.

I need program settings for my sr 16

For most Alesis drum machines the best way to get programming is to find an identical unit and clone/transfer from it. Try a music store that sells Alesis.

A second possibility is to go to website(s) and download a SYSEX file to transfer via MIDI to the unit.

Ihave an Alesis D4 drum sampler.I have not used in several years I have hooked it up now an everything lites up but I cant get any sound out of it. with triggers or pads?

Some of the Alesis products have a setup and data memory backed up by a battery. It is POSSIBLE that your battery expired and took the sound memory with it.

Investigate if you have a battery in yours (buried in the guts) and check the voltage. It should be above about 3 volts.

If it is below that, replace the battery and find another unit to clone the data from.
