Hello everyone I am a noob here so pardon my lack of knowledge. I just got my first piece of Metasonix gear the mighty D-1000 I and love it and it sounded great. Then I tried tuning it and cant seem to figure out how to get it sounding right again. I read the manual and it says to put the tune knob at 10 o'clock til you hear it sound right but what position should the cv knob be placed at while adjusting? Does the level knobs position have any effect on the tuning? Anyone have any advice or tricks on how they have tuned theirs?

To get it to sound 'right"? Not exactly sure what that means.
But as on all Metasonix gear a little goes a long way-turn knobs
VERY slowly until you hit that "sweet spot". And for some reason the CV in knobs and mix knobs DO seem to affect the sound even with no cv in.

i put mine through my girlfriends bass amp yesterday. Oh my lord...

I just want to get it to sound the same as when I bought it. When trying to tune it where should I have the cv knob set at? Sorry I am new to all this seriously, i just don't get it

Try tune and cv at about 10 o'clock with mix to the max. Then start slowly to play with tune and cv maybe between 9 and 1!

All D1k sound a bit different at the same settings and nobody has the same favorite sound, so if you are looking for exact the sound in your head, you have to use trial and error to find it.

So I am still a little confused so does the tune knob control the sweep of the filter and the cv knob control the resonance? I just can't seem to figure it all out I so regret taking it open and messing with the trimpots any help would be much appreciated as I have no experience with cv and am a noob to the whole hardware scene. It just seems to squelch out of control and I am afraid I may have damaged it turning the trimpots so much! seriously, i just don't get it

It sounds like you have the trimpots turned WAY to high I would turn them all the way down til you hear no sound or the squelch that you are talking about and then slowly bring them up til you hit the spot.

What way do I turn it to get it to stop and can someone answer if cv knob is resonance and the tune knob sweep the filter?

What does the cv knob do control when nothing is plugged into it?

I am still having problems getting it to not squelch and sound with a defined pop to it that it used to have. Please can someone tell me what the cv level knob does while adjusting the trimpot, if I should just leave it wide open while adjusting the trimpots or any other tips on how I can get it to not sound out of control the whole time (when I turn it on run and flip the switches in a sequence there is no break in the noise on drum 1 and 2) the snare and cymbal are working normal but I have spent hours on end trying to get a sound break in the 1 and 2 drums but its just drones and screams without a defined break in between hits? It now has such a small range of what I can get out of the knobs anymore where as when I purchased it I could get a wide range out of it now its just a little area of the knobs I can get sound out of and the volume levels are all different now too. Any tips would be very valued and appreciated. Please help Mr. Metasonix!

You have to turn the resonance down. The D-1000 drum circuits are filters that are set to be at the edge of oscillation.

The resonance is set by the 3 trimpots under the D-1000 PC board. You'll have to take it out of the toolbox cabinet and power it up. Set the CV level to the 12-o'clock position and the tune knob to about the 11-o'clock position.

That should be at roughly the center of the tuning range. Then adjust the resonance trimpot under the board for that drum sound, using a small flat screwdriver (like a jeweler's screwdriver), until the drum is just barely not oscillating (it should howl somewhere in the midrange frequencies).

The trimpots are turned COUNTERclockwise to increase resonance. Set each trimpot to just below howling.

DO NOT set the Tune knob for a bass sound when adjusting resonance. These circuits are more prone to howl at higher tuning settings, and you want to avoid howling all thru the tuning range.

Do this for all 3 drum circuits. Then put the D-1000 back together. Keep the CV Level at 12-o'clock and start playing the drum with the ROLL button. Adjust the Tune knob so you can get close to the pitch you want. The CV Level knob feeds it a small DC voltage when you're not putting in an external CV, so you can use CV Level as a fine-tuning control. Yes, I'm sorry, it takes a bit of patience.

I have posted a short article about resonance adjustment, with photos, on Muff's Wiki.

If you can't do this, there's nothing else I can do for you except to have you return the unit for adjustment.
