Hi all,

Can anyone translate the low/high pass numbers (1-100) on the MPC 2500, to frequencies?

I usually just use my ears when I'm setting low and high pass, which I'm sure many will say is the best way. But sometimes it would be useful to know what frequencies I'm cutting, especially as I often read articles which recommend keeping certain instruments around certain frequencies for the best listening.

For example, when I started on the MPC about a decade ago, a friend told me to low pass the bass to about '20'. I did this for a long time, but sometimes I'm going higher and sometimes I'm going down to about 10-15, which sounds good to me, but it would be helpful to know what frequency I'm at so I can make a better judgement about whether I should be increasing or decreasing this number!

I hope this makes sense...

In this situation I'd rather use my own ears than numbers.
You can also run your mpc audio into a computer frequency analyzer software to see what frequencies pass through as you play certain samples.

You can find out yourself, this one is freeware, play samples and twist the low pass and see what freqs show up. No I don't use it, I just looked it up.

So if you can establish the frequency range for each type of filter, you can work it out and share your findings with the community. Otherwise, use your ears, train them.

This one is for the MPC4000, comments in an envelope to Blue Haze. I printed this out years ago for reference.
