New Video of the harpejji with Auto swell

[Marcodi]

Hello all,
I just wanted to let everyone know that we have just placed a brand new video of the harpejji on youtube with the auto swell feature the is unique to the harpejji. This video was captured while we were showing the harpejji to Phil Keaggy and his band.

Feel free to post any questions on this thread or on our own forum.
Take care to all and have a great weekend!

ni-i-i-i-ce! Creating quite a stir at the concert.
I noticed that ric slowly moved sideways as if he wanted to play it from the side.

Can you "hear" Holdsworth?

Beautiful.

Nice clips. Good sound quality too. Makes me wonder what Steve Howe would sound like on one.

The autoswell is a nice addition. Does the auto damping use some sort of fret scanning? If so, then you are only a couple of steps away from a fret and string scanning MIDI. That is the method I used for the MIDI StarrBoard, and it worked very well.

John,

If I understand your question correctly, then the answer is YES. Every fret of the harpejji is electrically wired underneath. [Actually, we've been building harpejjis this way since Day 1, but without the mute/swell feature.] Because the strings and frets are both made of metal (low resistance) we can treat the string itself as a mechanical switch which completes an electrical circuit when fretted. So, that's the control signal.

STRING UNFRETTED: MUTE the audio out
STRING FRETTED: UNMUTE the audio out

Agreed; adding MIDI is not too far a leap.

That swell works well.Have you sold any Harpejjis to the UK yet? If so i would love to go pay the buyer a visit to try out this fine piece of kit!

Congrats on a good video! Keep em coming!

I have thought that it might be cool to build a guitar midi system where the string - fret contact generates the note instantly, and then you have a pitch to midi module that further refines the pitch and tracks bends and vibratos. The goal would be less latency.

So far we have not crossed the pond just yet. Once we do, we will make sure that everyone knows.

Craig,

If you want to fly me out, I'd be happy to demo mine once it arrives ;)

This system was developed on Wal basses in the 80's, and licensed for use on the Peavey CyberBass in the 90's

The synthaxe used to do something somewhat similar, I think.
There was no pitch to midi but direct sensing of the string and fret on the neck plus some vibrato / bending sensor. The 2nd set of strings (the plucked / strummed ones) was used to determine velocity, sensitivity, etc.
I guess that the instrument was too far ahead for it's time... I wonder if somebody tried to redo something like that with current DSP technology.
