My wife just picked me up a used Fatar CMS-61 keyboard controller from a church that was getting rid of it. (Ain't she sweet?) The church people said that it worked, so I will take them at their word. They are church people, after all. ![]() Anyways, I can't get the darned thing to work. It is getting power, and my MIDI setup works with the synth that I already have. I'm wondering if it has to do with the pedals. The CMS-61 has two jacks for pedals: one a sustain pedal, the other a volume pedal. Unfortunately, the unit did not come with the pedals (and my wife didn't know it was supposed to have them...) And on a related note: If someone could explain to me how a keyboard volume pedal works, I'd appreciate it. This is a pedal that simply plugs into the keyboard via a 1/4" jack. It's not the kind where the instrument plugs into the pedal, then comes out the output and plugs into the amp. I know how they work. Anyways, I'd really appreciate any input. Do you think not having the pedals connected is what's causing the problem? Does a volume pedal of this type send MIDI messages into the keyboard? Or does it do its work some other way? And if I do have to get a pedal for this, exactly what kind of pedal am I looking for? (I.e., what specs should I look at to know it would work?) I did try the one guitar effects pedal I have, but that didn't do anything. Thanks for any insight you can provide! --- Ed ------------------ IP: Logged |

I am no expert on the particular equipment in question, but I can't believe that lack of a pedal would cause you a problem. When you say it doesn't work, what do you mean? Is it not sending midi data? Plug it into a module that has an LED that indicates midi input. If it lights--or not--should help you torubleshoot. Are you certain that you are sending and receiving on the same midi channel? If you are usingamidi patch bay, or a computer, I would recommend that you plug the Fatar directly inot one module. simplify. Then see if it works. Try to determine, on the most basic level, if the controller is sending midi. If it is, then you have some match-up problem in your system. If it isn't, then it's broke, or has a bad setting somewhere. I sounds to me like the volume pedal is sending midi volume data. IP: Logged |

The pedal is just an (overpriced) potentiometer in a big box. Circuitry inside the keyboard measures the resistance and converts this into a MIDI Continuous Controller #7 message whenever the pedal moves. If there is no pedal plugged in the circuitry sees an open circuit all the time and so will not generate any CC7 messages. There may be a knob on top of the keyboard that sets a base setting for CC7 - make sure that is not at zero. Wrong channel number is the most common problem. Using a breath-sensitive patch without a breath- or aftertouch input is more obscure and probably not your problem. IP: Logged |

Thanks for the input and the info. The problem, just to clarify, is that the keyboard does not appear to be sending MIDI data. But I am finding that difficult to verify, partly because I don't have a whole lot of equipment to test on. I just plugged into my computer, brought up my sequencing software, hit some keys, and nothing happened. So I pulled the "MIDI In" plug out of the keyboard, plugged it into my other synth, hit some keys there, and out came music. I did check that the send and receive were on the same channel. Unfortunately, this keyboard has NO display! So you punch some buttons to set a MIDI channel (or anything else), and you just have to go on faith that it did indeed change the setting like you asked it to. Supposedly it resets to channel 1 when you first power on, so that's at least a little objectivity. Part of my thought on the pedal was that, suppose the last person to play it brought the volume pedal down to zero, then unplugged the pedal. Would that volume setting then stay at zero until you plugged in another pedal and cranked it up higher? Since I didn't even understand how the pedal worked, I had no clue. There is also a wheel on top that you can set to control volume (or a few other settings). I did set it for volume control and turned it all the way up. Still nothing. The manual, which I downloaded from the web, is less than helpful on all this stuff.... At least now I know that the pedal sends electrical signals rather than MIDI data -- that could be some help. I didn't have a chance to tinker today, I'll try a few more things and see what happens. Thanks again! --- Ed ------------------ IP: Logged |

The cable should be connected to the MIDI *out* on the keyboard! The keyboard has no memory of where the pedal was. In any case, the pedal position does not prevent MIDI messages from being sent. Your sequencer probably has a MIDI Monitor function somewhere. Use that to see what is arriving. Do you have any other MIDI controllers that DO work when plugged into the computer? It is easy to have the sequencer looking in the wrong place. IP: Logged |

The keyboard only has a MIDI out -- no MIDI in. Guess I phrased that sentence a bit fuzzy up there... (I meant the MIDI In to the computer, which is plugged into the MIDI Out in the keyboard...) And, yes, my other keyboard works just fine. I can just pull the MIDI cable out of the bad keyboard and plug it into the good one -- voila! music, without making any other changes. So obviously the problem is in my new keyboard somewhere. I think it's pretty clear that the keyboard is not sending the MIDI data. I'm just stumped as to why. I suppose there is always the possibility that the church people were not completely honest when they said it worked.... Thanks for all the help, I'll let y'all know if I ever do figure this out. --- Ed ------------------ IP: Logged |

Try this. Set your sequencer to record all 16 MIDI channels into one track. (This will be in MIDI setup somewhere.) Record-enable the track. Hit record. Then hit a few keys on the new keyboard, then hit STOP. Now you can use the EVENT viewer to see what, if anything arrived. It might be sending on a channel different from where you think it was. I had a keyboard once that wanted to send on CH 11 all the time. IP: Logged |
