Quote from: Elantric on June 21, 2008, 06:13:42 AMIts odd you are using a FV-50 as an expression pedal for the FC-300Two versions are availableFV-50H = High Impedance = 500K ohm ( for Guitar)http://www.bosscorp.co.jp/products/en/FV-50h/index.htmlAnd FV-50L = Low Imedance 20K ohm ( for Keyboards)http://www.bosscorp.co.jp/products/en/FV-50L/index.htmlBoth are stereo volume pedals, intended to go in the audio signal pathNeither are recommended nor designed to be used as a VG-99 Expression pedal.The Larger Boss FV-500 H and L models have dual pots for volume and expression. Exp pots are 10K linear, so it can work as a 10K Expression pedal.The Roland EV-5 is the Expression pedal Roland intended us to use with VG-99 / FC-300 extrernal Expression pedal Control Jacks.http://www.rolandus.com/products/productdetails.aspx?ObjectId=54It is 10K control via TRS Phone plughttps://www.vguitarforums.com/smf/index.php?action=dlattach;topic=33.0;attach=821;imageTip = Control element - sweeps from 10K to GroundRing = fixed 10K reference for control circuitGround = Electrical shield to minimize noiseI'm surprised you can get the FV-50L to work as an expression pedal with the FC-300 The EV-5 schematics are pretty clear on the circuit required. (see below)The VG-99 / FC-300 Owners Manuals are quite clear - Use the EV-5, which is a different beast than the FV-50L.( I use a FV-50H on my stompbox Pedal Board)I have three EV-5 pedals, and they are each 10K linear.(actually measure 8.9K ohm)I use them all the time with my Line6 gear and VG-99 - plug and play.I understand the Line 6 Expression Pedal is an EV-5 clone and should work fine with the VG-99.Fullcompass sells them for $43http://www.fullcompass.com/product/249896.html

You are correct that most sustain pedals are momentary, but the ones we are talking about are not.
QuoteI am ordering a FPU-3, which I understand has the same pots as the DP-10 and will report back if it is successful as an expression controller with the GP-10.

Quote from: Markwaaron@icloud.com on May 11, 2018, 04:42:04 PMRPU-3 received, and not much luck so far. I am learning a lot about how to program the unit from the boss editing program. Having a lot of trouble deciphering how the basic b-bender program works and how to translate that into something that is controllable by exp 2. I can't decide whether the unit simply does not work on the exp 2 in socket of the Gp-10 or whether it's my lack of knowledge about how to create a patch that will allow an exp 2 b (or other string) bend. Any insight would be appreciated.
QuoteRe: EV-5 expression pedal for FA06Postby locojohn » 22:35, 6 July 2017Am I alone here using Roland RPU-3 for everything, including expression control? As noted above, there are settings on the FA that can reverse polarity and make any of its 3 pedals operate as expression control, hold pedal or tweak any other continuous parameter. Haven't tried foot switch type parameters yet, but overall I am enjoying having all 3 pedals in one sturdy and seemingly reliable piece.Postby locojohn » 23:20, 6 July 2017Escaperocks wrote:How do you precisely control expression amount with what is basically a sustain pedal? I.e., there are times I need to leave expression at 90, them move it to 127, then back to zero.As mentioned, all three pedals in RPU-3 can operate as continuous controllers, meaning you can assign each to, say, control volume changes or send a "soft pedal" effect. Indeed, what you mentioned isn't possible with a pedal that has a full fixed range. But if you just use expression pedal to lower the volume, then you can do it with RPU-3 as well..
QuoteGood weight and very well built. The 3 pedals are continuous, using potentiometers. They are of the normally closed type (low impedance) , and go to progressively to higher impedance when pressed. They are terminated with 3 stereo jack plugs, so should be easy to use with a variety of keyboards.
