Your assumption is correct. If used as a volume expression pedal for keyboards and synthesizers (via a TRS cable), the knob on the side is to define the amount of volume in the minimum position. If you only want to decrease the overall volume a bit, turn it towards the MAX position, if you need the sound to vanish completely, turn it to the MIN position.Steviebone wrote: ↑Tue Aug 23, 2022 5:03 amWhat is the max volume on a stomppedal? In other words, what knob am I setting on the pedal? Is this whatever parameter the expression pedal is supposed to be controlling?
For example, lets say I want to control rate... am I setting the minimum and maximum range of the pedal by turning the rate up as high as I want it to go, depress the treadle all the way, then move to heel and set the minimum? I'll try that... doesn't make any sense though. So what happens when you touch the knob later?
This does also work with BOSS pedals with an expression pedal input, like the old FT-2, the PH-3 or the RT-20, etc., where it has no effect on the volume. Also many synthesizers have an assignable pedal input where this expression pedal can for example control the filter cutoff.
This is because this pedal was mainly designed to be used with keyboards and synthesizers. These are the 'instruments' the manual is referring to. In the global settings of those instruments you can often define the range of expression pedals so they can work with pedals of different brands (for example Roland expression pedals have a range from 0 kOhm to 10 kOhm, while a KORG EXP-2 goes to 50 kOhm). So the synthesizer is then correctly calibrated for the minimum and maximum values of the used expression pedal.Steviebone wrote: ↑Tue Aug 23, 2022 5:03 am"depress and set the volume of the connected instrument" is non-sensical because there is no 'instrument' connected and I'm not setting volume.
But some pedals like the BOSS DD-7 have enhanced functions for an expression jack where this calibration that Old_Iron quoted is quite relevant as well (read the DD-7 manual in that case).
To sum it up:
- You want to use the FV-500H pedals as expression pedals for your BOSS pedals.
- The excerpt of the FV-500H manual (that Old_Iron quoted) says: "The FV-500H is similar in design to the Roland EV-5 Expression Pedal and therefore can be connected to the EXP PEDAL (EV-5) jack on Roland BOSS products."
- If the expression pedals don't come with TRS (stereo) cables, you need to purchase them separately to make the expression function work.
- Some digital BOSS pedals have enhanced expression pedal functions, so you need to read the parts of those manuals that explain it.
- If you use pedals with basic expression pedal function like the FT-2 or PS-3 you simply need to plug the FV-500H with a TRS-cable into the EXP jack (you can simply adjust the "Minimum Volume" knob to your desire in this case).
