Hi, I have a Ludwig Classic Maple drum comprising: Bd 16x24, Sr 5x14 , Tt 7x10, Tt 8x12 , Ft 14x14 , Ft 16x16 . I am very happy with the sound of this drum, very powerful, resonant, and easy tuning, I have some problems with the kick, the sound has much attack, but lacks body and is weak at low frequencies, you tell me how can I have a sound Kick better? .. Thank you very much. David.

Videos manuals, or do you think you have a fault with it?

Mida, you are in the LAWN MOWER section

Go to YouTube and search for "Bass pedal" There are many videos. Select and view ones on "setup" and also view "technique". These will solve the problems you are having.

Actually, ONLY TWO pins are used in the MIDI cable. The data is sent serially at a 31.25KBit rate.
You probably need to "map" the ones that aren't working into the appropriate codes to trigger the SR-18 sounds.

You need to COMPARE the codes sent from the DTX to those needed by the SR-18.

There also may be options in the DTX for type of drum kit such as "Latin" and selecting one of those may have the mapping already done.

In the literature of each device will be a list of the MIDI codes the DTX generates and those required by the SR-18.

essentially the percussion codes are NOT standardized completely between devices... but there is usually a way to "map" them to make it work.

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.

The SR-16 uses an external transformer as the power supply which provides 9 volts AC. This ac power is converted to DC positive and negative voltages for the digital and analog portions of the circuit. Although the unit has been reliable generally, this symptoms sounds like of of the main filter capacitors in the DC converter circuit(rectifier, filters and voltage regulator) has broken loose or is defective. This will affect both channel equally. If the problem is in one channel, a broken shield on a cable or the output jack ground connection might have broken on that one channel.

Buy the correct adapter that matches the voltage AND current requirements of the unit. MANY universal ones do not and the original MAY have built in filter that universal does not.

You MAY also need to do a factory reset on the unit.
