We have now been able to replicate the problem. Thanks to nullin for help with this. Now we’re trying to figure out what the cause(s) of the missed MIDI messages are.

Can you try the same set up but using the DXMB’s power supply? The DXMB draws about 100mA.
If the heart beat sound goes away that means the Fuel Tank is not supplying enough power. If the heart beat still persists, then I’m not sure what it is at the moment.

Overall, I am happy with the pedal apart from one issue that is beginning to bug me.I have the pedal in my amp’s fx loop and when my amp is on it’s drive setting, I can hear a rather annoying ‘heartbeat’ sound that is sync’d with the the tap tempo rate. I’ve checked all the patch cables, etc, but can’t seem to get rid of the noise. Is this to be expected or do I have a faulty pedal?
The ‘heartbeat’ noise doesn’t seem to be there when the pedal is put into the front of the amp rather than through the loop.
Anyone know how to fix this?
How are you powering the Deluxe Memory Boy?
Flick (EHX Staff)ModeratorQuote:I’m having a similar issue. My 8 Step works just fine so long as I use the control panel. It does not respond to MIDI commands other than Clock. I’ve run several tests, for example sending a PC on the same channel as several other devices and all the other devices take the command just fine, but the 8 Step does not respond. Actually, it will randomly, and only very occasionally, start flashing the current preset number, but it will not actually load anything, and there appears to be no consistent rhyme or reason as to when this will happen. Most of the time is simply does not respond. Worse for me is that no one (stores) in Phoenix, AZ seems to have one yet – at least that I am aware of – so I cannot easily get hold of another to check that it’s just a fluke with the unit I got from Sweetwater. Any help on this would be great. I love the concept of this box but without the MIDI functions it doesn’t serve my needs. Is there an easy way to swap the one I have for another than is confirmed to respond fully to MIDI? Thanks in advance. Hoping to hear back for you all. -MaxCan you give us some examples of the PC message numbers you are sending to the 8 Step? From the factory, the 8 Step has presets in locations 0 through 9, which would be PC messages 1 through 10 for most MIDI devices. If you send a PC message for an unsaved preset location, the 8 Step ignores the message. Try sending PC #101 while the 8 Step is running, does the 8 Step pause or does it reset to Step 1 and keep going? Does it not do anything at all? If PC #101 pauses the 8 Step then add 1 to each PC message number in the 8 Step’s PC message table, on page 23 of the 8 Step’s manual.
Also the 8 Step must be set to the MIDI master’s MIDI channel so double check the 8 Step is set to the correct MIDI channel. Look to Page 20 of the manual for instructions on changing the MIDI channel.

For any pedal that has a MIDI input, the designers should make every parameter editable via a MIDI command. That way your sequencer could be like an endless supply of 8-Step Programs, and you wouldn’t need to bother with CV.
While we’re waiting for that, you can always get a MIDI to CV interface. I have the Doepfer Dark Link. It controls multiple expression parameters. See my demo here http://youtu.be/U5TS7-DK_cM
If you want to keep it simple and elegant, keep it on the floor, if you don’t already have MIDI – or a whole other bunch of reasons including that it’s cool, go with the 8 Step Program.
The 8 Step is fully controllable through its MIDI IN port. All parameters are editable through MIDI CC. Many functions can also be accessed through MIDI Program Change. So you can actually use the 8 Step as a MIDI to CV converter.
Flick (EHX Staff)ModeratorQuote:” the fact that it continues to respond to MIDI clock after it stops responding to MIDI CC is a little puzzling.”To say at the very least. I will be sending the unit to you guys directly and maybe you can confirm that I’m not crazy. I understand how controllers can sometimes skip values in messages sent being encoder based but I don’t get this level of error with my other gear. Sounds like your stress test is going well and I wish you luck. I also greatly appreciate your cooperation and the fact that you are taking a deeper look into possible flaws, it’s quite reassuring.
I just sent a PM to you, please check it before packing up the 8 Step. Thank you for your patience and helping us understand this problem.
Flick (EHX Staff)ModeratorWe’ve been slamming an 8 Step with around 64 CC messages per second for the past 18 hours and it hasn’t crashed or frozen, so I think your unit has a hardware problem. Although the fact that it continues to respond to MIDI clock after it stops responding to MIDI CC is a little puzzling. We’re going to spend more time on this today.
Flick (EHX Staff)ModeratorIs the 8 Step syncing to MIDI clock through all these failures?
Flick (EHX Staff)ModeratorWe are conducting some tests using Ableton Live at the moment, sending out a continuous stream of multiple CC messages to the 8 Step.
When you use the hardware controllers, are you occasionally moving sliders, knob and buttons, like one every other second or slower or are you constantly moving multiple sliders?
Flick (EHX Staff)ModeratorQuote:So I am running the 8 Step Program into my Moogerfoogers (CV out to freqbox ‘frequency input’ with ‘osc out’ direct to a midimurf for tonal and rhythmic shaping) and attempting to use CC midi control from an Evolution UC-33e and I find that when the 8 step first powers on, it responds to the controller just fine up to so many messages and then it doesn’t seem to respond to midi any more unless I reboot. This happens pretty much 10/10 times. It works fine at boot up and then suddenly stops responding to messages as though it has a small midi buffer that is easily overwhelmed. Any one else verify this or is my unit showing signs of defection?Otherwise the on board controls work great and I love this pedal for making my other pedals shine like a modular synth. Couldn’t get that level of control before at such a great price. Just disappointing that the midi keeps failing. Any help is appreciated, thank you.
We haven’t seen this problem where it stops responding to MIDI data in our tests of trying to overload it with MIDI data. Which CC(s) are you using? Which channel do you have the 8-Step set to?
You could try a factory restore, this is on page 19 of the manual. Doing this will erase any presets you might have made.
The most likely problem might actually be something wrong in the hardware, in the MIDI circuit.
Flick (EHX Staff)ModeratorQuote:Thanks. So there is no way to stop track 2 for example, and let the other ones continue playing? Appreciate your reply.In addition to simply bringing down the Track 2 fader as Mr. Grim says, if you use MIDI with the 45000 you could also mute Track 2 directly with a MIDI PC message.
Flick (EHX Staff)ModeratorQuote:Hi, I’m close to buying a 45000 but need to know if the “stop” button, whether on the main unit or the foot controller, stops all the tracks at once, and if “start” starts all tracks at once too. Thanks for your help.The PLAY button starts and stops all tracks simultaneously. Think of the 4 tracks and mixdown track as if they were on tape, the entire tape would start and stop, that’s how the 45000 works.
Flick (EHX Staff)ModeratorQuote:Sorry to resurrect this ancient thread, but…For me, it’s definitely temperature where the Memory Boy is concerned. No question.
When I go to the drafty rehearsal space and put it on the floor, the max delay time goes down. If I put it up on the vent of my warm amp, it eventually returns to “normal”, but then it’s awfully hard to stomp on. Note – same power supply plugged into the same socket, whether on the floor or on the amp. Back in the studio, it always behaves because I keep it in a nice warm corner of my gear rack, which keeps it at a constant 80F or so. That solution only works because I don’t need to stomp on it there.
[strong]Does anyone have concrete experience with the Deluxe MB[/strong]? Does the delay also get shorter with colder temperatures? If it’s immune to temperature, then it’s problem fixed. But, if the problem is only masked by the tap tempo, then the problems’s only fixed as long as you don’t want a long delay near the top of the dial in a cold room.
/d
The Deluxe Memory Boy does not have the delay time vs. temperature issue, at all, it is fixed in that product.
Flick (EHX Staff)ModeratorQuote:Hi. I’m not an electronics guy, so bear with me. My goal is to use two DDMTT pedals in parallel and control the tempo of each with a single tap, so they are synchronized. The poor man’s solution would be to angle the pedals in such a way that I could stomp on the tap buttons from both pedals at once. What I want is to tap on one switch and control both EMM pedals. The manual says:“TAP SW Jack — Allows the musician to input the tap tempo from an external momentary switch. . . . A suggested Momentary Footswitch that has been tested with the DDMTT is the Boss FS-5U Momentary Foot Switch.”
Questions:
1. Could you Y the output of a single footswitch so that it controls the tap of both DDMTT units?
2. Has anyone tried this, and if so, how did it work?Disconnect power from both DMMTT pedals. Connect the two TAP SW jacks together with one standard TS cable. Press the TAP FSW on either pedal and it will engage the TAP function on the other pedal.
Flick (EHX Staff)ModeratorQuote:Quote:The 8-Step is not compatible with the Line 6 pedals we have tested (DL4 and MM4) and we can assume it is not compatible with any Line 6 gear.Heya Flick
could you guys wire up a test cable/converter box to try with the 8step?
Most of the L6 cv applications are done with a 10K treadle on a mono/unbalanced cable
so taking the balanced/stereo out of the 8step, wiring it so the 8step tip is to the L6 output tip, the 8step ring is to the L6 output ground/sleeve (with a either 13.3K or 12.2K resistor in line to lower the signal range, I forget which is appropriate off the top of my head) and the 8step sleeve going nowhere.You can connect a TS cable to the output of the 8-Step, the 8-Step then outputs a total range of 0 to 5V on the TS cable. We tried connecting the TS cable to a L6 pedal, still no luck. In this scenario the Ring and Sleeve are shorted to GND. We will try putting a 13k resistor between the Sleeve and GND.
