Hitting RECORD a second is the same as giving it the MIDI START command. The first time you press RECORD, the 2880 puts itself into a Record Ready mode, this is when both the EXT CLOCK and RECORD LEDs blink rapidly. The second time you press RECORD the 2880 begins recording using the MIDI clock to set the tempo.

Normal operation on the 2880 when recording a NEW LOOP while syncing to MIDI Clock goes like this:

1. Connect your MIDI cable to the 2880’s MIDI IN port. Set up your master device to produce MIDI CLK, preferably all the time. I’ll assume that the device is producing MIDI clock all the time in the following steps.

2. Enable EXT CLOCK and optionally, though I highly recommend, also QUANTIZE mode. Both LEDs should be lit above their respective buttons.

3. At this point you can check if 2880 is receiving the MIDI Clock correctly by changing the tempo on the master device while looking at the blinking CLIX LEDs. A tempo of 300 will cause the LEDs to blink rapidly. A tempo of say 130 will give you a medium speed blink and a tempo of 50 will be a pretty slow blink. If you see the changes in the blinking LED speeds then the 2880 is correctly receiving MIDI clock.

4. Now to record a Loop: Press the NEW LOOP button, the RECORD LED will blink. Press the RECORD button, now both the RECORD and EXT CLOCK LEDs should be blinking. At this point the 2880 is in record ready mode and is waiting for the user to either press the RECORD button or to receive the PLAY command from the MIDI master; either will cause the 2880 to begin recording the new loop. If you have QUANTIZE on as well, it will go through some portion of the 4 beat count-in. The 4 beat count-in picks up where ever the master happens to be within a bar at the time you press RECORD.

5. When you want to finish recording the loop press PLAY, the 2880 will begin playing back whatever you recorded on Track 1 and also begin recording on Track 2. If Quantize is on it will either finish out the bar or truncate to the end of the previous bar.

6. In step 4, if there is no MIDI Clock present when you hit RECORD the second time to begin recording, the 2880 will default to the last known good MIDI clock tempo or if no MIDI clock tempo had ever been present, it will default to the last setting of the TEMPO slider before enabling EXT CLOCK.

Tbe Hum Debugger will only cut out noise that is related to 60 or 50 cycle hum from wall outlets. The noise in the DMM is a broadband white noise.

Do you only hear the noise when you play notes? The DMM has its own built-in noise suppression circuit and you really should only hear the white noise when you play notes and on each subsequent echo. If you are hearing white noise at all times then something may be wrong with your DMM, if you are only hearing the white noise when you play notes and on each subsequent echo then there may not be much more you can do. The Boss NS2 acts in a very similar fashion to the noise suppression in the DMM.

The DMMTT uses four MN3005s which are scarce. We were able to buy enough to build around 500 units. We will build more if and when we can find more MN3005s. We do still have some of these units on our factory floor.

The shorter version (which will have a different name and artwork) will use the MN3008 chips which have half the number bucket brigades as compared to the MN3005, yielding half the delay time.

We are not taking MN3005 chips from the DMMTT to build the shorter version.

I don’t know what the price will be on the shorter version of this product.

800-900 of the DMMTT, not the shorter unit.

We have definitely sold more than 300. We should get about 800-900 units out there before the chips dry up again.
