what is the difference? i love the concept of the MURF but i’m worried it won’t be able to do the same things as the Moog 101 can.
also, if anyone in bc has gotten one of these products, please letme know. the site says no store except some store in ontario sells them.
MF105 is a set of fixed bandpass filters that can be modulated with a pattern generator.
MF101 is a low pass resonant filter with an envelope generator. Big difference is the filter has variable resonance and frequency.
Both very different boxes.
can the M101 be run by itself or is it ideal that it be set with other moog pedals?
It’s very good by itself especially with a GOOD expression pedal. But it is even better with the other MF pedals. The control voltage possiblities really make the pedals come alive.
would the moog expression pedal be ideal?
and if you have, say, two moog pedals,would you only need one expression pedal? i’m trying to nail something of an electronica/dance/trance sound from the song ‘the crystal method - keep hope alive’ on my guitar and am contemplating getting the phaser and the low pass filter.
oh and by the way, what does an expression pedal do? 
I prefer the Roland EV5 (street price about $50-60), and you can use more than one expression pedal as well as the CV outs of the other MFoogers. But you might find one enough for your needs. Or you could add the CP251 and get even more CV possibilities.
Simply put, the expression pedal is nothing more than a foot-controlled pot connected to a TRS Insert Cable.
When connected to a MoogerFooger CV input jack, the 'Fooger supplies +5V to the expression pedal on the Ring terminal. That voltage goes through the expression pedal and is returned (attentuated by the foot position) on the Tip terminal. So an expression pedal creates a variable CV that is controlled by the foot.
When used with a 'Fooger, the expression pedal will have an additive effect on the parameter it controls. For example, if the expression pedal is plugged into LFO Rate, the position of the LFO Rate control knob establishes the lowest rate, and the pedal increases it from that point. This makes sense since the expression pedal can only supply a positive voltage in the range 0-+5V.
Hope this helps.
thanks alot guys. this is great info
