New Project Drone/Delay

I have a circuit made that uses the Hex Drone Box sound base running through a delay circuit based on the PT2399 IC.  Makes some amazing drones.  Sound (square wave based) section is set, made some adjustments to the Separation portion and changed the frequency range.  Delay side is still in the works, but nearly complete.  I looked at a lot of different arrangements of the circuit, but ended up basing the design around the original schematic found in the specification sheet.  Of course I added a few changes :-)

I will post a video soon of the initial work.

I started a blog for my music project gebrochene augen.  The blog is intended to document my experience working with my latest project.  It will report all phases of the project from ideas, sampling sources, demo tracks to full audio just before release, if it gets released--I still need to work this detail out : ) .

Hex Box V2

I am working on an analog based signal device similar to the Hex Drone/Noise Box made previously.  I have plans to change the separation range and also add on-board delay via a PT2399 IC.  The delay will be based of of the data sheet design but will be simplified and built to work specifically with the CD40106 IC and its signal range.

More to follow !!

Drone Box Video

I made a short demo video for the Hex Schmitt Drone box.

 

 Volume is on the far right, the top two and the bottom two controls are the pair of oscillators (four controls total for frequency and separation).  About half way in I kicked some delay effects.

Quad Oscillator Drone Synth

I have been working on a new circuit based around a Hex Schmitt IC.  This offers 4 oscillators and two buffers.  The oscillators are controlled through four potentiometers.  The oscillators are grouped into two pairs with a dual pot for each pair and an additional separation control to individualize each pair.

Volume control on the output, on/off switch and a standard 1/4" output jack.  The circuit runs on 9VDC.

Enclosure is made of die cast aluminum and I gave it a sort of scuff polished looked; something different than paint.  Great small design is easy to handle or perfect for placement on a table amongst other great synths ;)

Audio sample was recorded with the signal pushed through a delay and phaser effect.  On its own this is a great source for some drone type soundscapes and textures.

Circuit Bent Casio MT-36

Just finished my latest bend, a Casio MT-36.

This one has an added filter (distortion and tone control), LFO and 5 glitches.  filter has frequency and separate tone control knobs.  The LFO has a Rate control and Amount control.  This keyboard uses a variable capacitor, rather than a resistor or crystal, on the CPU.  With this I used a potentiometer to adjust the amount of LFO signal fed into the timing cap.  This gives the sound out put a wobble or sequenced/ step effect.  At a high enough level, the LFO will make the keyboard loop and glitch.  In addition, there are 5 different bend points (glitches) that I included and are activated by 4 switches.

Output is via the standard (on bard) 1/8 output jack.  Runs on the standard Casio Power Supply (7.5 VDC)
