  1. Hello! I'm trying to figure out a problem with MIDI expression pedal messaging (CASIO SP-32 three pedals) with CASIO PX-330 into my Macbook. The problem is that when the pedal is pressed, the volume jumps (too sharp a step) from 0% to 100% even with minimal pedal pressure. If you set the track to 50% volume (dynamics of playing strings) and press the pedal, the increase goes smoothly up to 100%, but when you release the pedal it goes back to 0... and then 0-100% when you press again. Connection sequence: 1. I connect the PX-330 with 3 CASIO SP-32 expression pedals with a USB cable to my computer. 2. I turn on Logic X, add a pedal signal converter VST (step 3) and a orchestra VST (BBC Symphony Orchestra free) to a new track. 3. In the converter I select the incoming signal of one of the 3 pedals, for example, 66 Sostenuto and convert it to CC11 Expression. See screen: Tried different values of Scale and Add scales - makes little difference. 4. I try to play some melody with the pedal and hear the volume jumping jerkily 😪 For some reason I also can't use Learn mode on this or that control in an orchestral or other VST plugin - it just doesn't learn 🤔 ... so I have to convert the signal with modifier. Possible solutions: 1) In a neighboring forum thread about the same problem on the PX-560, users eventually write that updating the firmware solved this issue: But I don't see where to download the update for the PX-330 and whether it solves my problem. And many people write that the update can damage the device board (Please Wait mode) and I'm afraid to get a brick instead of a device. 2) Another one of the solutions I found in the vastness of internet forums is to buy an Ashby Solutions FC7 adapter: https://www.logicprohelp.com/forums/topic/65084-expression-pedal-volume-jump/ First, as I understand it, the FC7 adapter uses a 6.3 jack, but my SP-32 triple pedal uses its own plug to connect. So, you have to use an additional pedal via the 6.3 jack. Second, the Ashby Solutions FC7 adapter is no longer in production (or made in pieces on request), as the manufacturer itself notified back in 2021: https://forums.musicplayer.com/topic/180605-does-anyone-still-use-the-ashby-solutions-adapter/ What can be done here to solve this problem?
  2. Problem: PX-560 | CC doesn't provide smooth volume control when pedal is assigned to CC11:Expression I bought the M-Audio EX-P expression pedal. Calibrated and assigned it to CC 11 controller so I could control volume with my foot. I returned it back because it seemed to be causing a very noticeable volume jump just as the layer fades in. I was expecting the expression pedal to increase the volume smoothly, just like when you use the keyboard's master volume knob, but that's not what happened. Initially, the sound jumps from off to some low level; and it's definitely a jump and nothing like a fade in. As I further depress the pedal, it's not smooth at all in the first ~25-33% of travel. Once I'm past that first third of the travel, the pedal seems to operate smoothly. But it really kills anything subtle you're trying to do at lower volume levels. So I bought the Moog ACCEP003 EP3 expression pedal. Plugged it in; calibrated it, and same thing - volume jumping at initial fade-in and then along the first 25 - 33% of travel. Kind of like a detented pot, if you know what I mean by that. It's looking like my PX-560 is the problem. Now it could be just my keyboard, but I'm thinking that people just haven't noticed it yet because they're fading in a sound while another sound is already playing so the problem would be masked. That other sound could be coming from their own keyboard or their band mates' instruments. Either way, it probably wouldn't be noticeable. Took a while before I caught it. Anyway, I'm assuming this problem exists for all PX-560's. I'm guessing it's a firmware issue where the code/function that interprets and translates the pedal's variable resistance/impedance at its lowest levels is not granular enough to produce a smooth continuous controller response over the entire range of travel on the pedal. Maybe it's a problem having to do with the characteristics of the pedal's potentiometer, but I'm betting that routine could be written that notices when jump in db is about to happen and branch off to a subroutine that smooths out that volume level transition over time. You'd have to have to play with the timing so that is sounds natural/believable/reponsive, or as close to it as possible, but I bet could be done. Thoughts? Thanks!
