I already sold a couple and there are some other others who showed interest so I am giving them a chance to get some first.
But if there are any boards left you're next on the list. There will probably be another run though. And yes I do want to make
panels, I need them myself anyway. I ordered some transfer paper from china to see if I can get good results with the
toner transfer method (will take a couple of weeks before that arrives). Another option would be using PCB material but
eagle lite doesn't support the panel size. So I have to find something else to design that with and figure out how to import an
image exactly to scale (I did make a design).
Phobos helped me out when I had a wee anomaly on the breadboarded V2.1 circuit , thanks again .
I had an idea for something using the wave wiper and done some tests to see what happens when running 2 wave wipers in series and also to see what it sounded like with FX / filters / wave folder / 5pulser etc between the wipers almost like a send & return loop , the results were that pleasing I have decided to build a 4 wave wiper module .
I was initially thinking of having 4 fully modular wipers , and changed my mind to have 2 fully modular ones with a slave wiper under each with an added cross over switch to swap over output 1B and output 2A , which will be wired through, going into input 3B and input 4A, also a couple of veroboard simple LFO's
The diagram below is showing the inputs and outputs & how the cross over switch operates in the middle and the lfo destinations.
The bottom file is version 4 of trying a few hardware layouts ( to be turned skrog blue once im ready for ordering a panel sticker) .

I recorded some of the tests I wanted to try with my breadboarded wave wiper (s), here are some mp3s & descriptions of set ups .......

1 wave wipe saw & squ in +lfo.mp3
Description:
one wave wipe with a vco square to in 1A and separate vco saw into in 1B , I am swinging the wipe set pot to start with then turn up the cv input which has a Mfos LFO patched up.

2 wipes in series seperate lfo's to each.mp3
Description:
2 wave wipes in series with a separate LFO into each cv input , again turning the wipe set pot and adjusting speeds of the lfo's , same inputs as before but changed the pitch of one VCO.

2 wipes series with Mfos wave freaker inseterd between.mp3
Description:
2 wipers in series this time with a Mfos wave freaker patched as an insert FX between output 1A and slave wiper 1A input , the wave freaker has a frequency divider & fold/ shape type actions , adjusting lfo speeds & amounts & wipe set adjustme

2 wipes series with 5Pulser inserted beteween them.mp3
Description:
2 wipers in series with a ian fritz 5pulser inserted between first wiper out 1A and slave wiper in 1A I use a slow lfo to hear the stepping sounds and adjusted the speed for lfo 2.

2 wipes series with delay FX between them.mp3
Description:
this one I tried a delay FX between the wipers ,a dual sequencer is now playing the 2 VCOs , turning the delay time up & down, and adjusting the lfo speeds ..... at the very end of this file it sounds like a modular Status Quo riff , hehe , new terri
Thanks for the samples.
I was wondering what it sounded like with harmonics of the same wave in both inputs, the 5-pulser gets in that area.
and
that Glaswegian drunken slur at the beginning of the last one is a good indication of the possibilities!
Boards arrived early in the week , thanks Phobos , snapped off the top boards & got to work soldering the diodes / resistors / ic sockets / caps etc onto the 4 main pcbs .
Also finished the final layout on the panel (100mm x 250mm) , legends converted to blue and was thinking about the lfo's controlling a series wave wiper stack each , both stacks lfo amount into 1&3 / 2&4 would be swept the same direction , so I squeezed in 2 extra switches , one inverts the respective lfo1 / lfo2 into the slave wipers only, and the other switch will swap lfo 1 & 2 over (lfo2 to wiper 3 , lfo1 to wiper 4)
Hope to get the final sticker design ordered through next week sometime.

First mp3 is 2 vcos sync'd together with square from 1vco and saw from 2nd vco going into wiper 1 & wiper 3 (left hand series stack) . A sequencer bass line runs the vcos and various combinations of internal & external lfo's / sequencer cv was tried on the cv inputs.
Second mp3 is a droney track , fed a differently modulated vco to each wiper (drums plugged into wiper 4), adjusting cv inputs & lfo speeds and wipe set positions.
Find it hard to discern what's happening without an oscilloscope

Hullo
On the first set of demos , I had the outputs connected direct to a stereo channel on my mixer , with headphones it was easy to hear the sound sources being flung side to side with different modulations.
The mp3 "2 vco's in sync" , I used the W4ve wiper in a typical mono bass line patch up ...vcos / wipers / vca / mixer , it is acting as a type of bass line fattener almost like using something like Ken Stone wave folders to spice up a "plain Jane" synth line.
When patching up lots of wipers in series , I found just using a single output from the end of line wiper worked really well , when patching the 2 outputs of a full series chain of wipers to the built in 4 ch. mixer of my vca ( no panning) there was occasional cancellation and also distortion depending on where the wipe dials were set , but that is understandable with both outputs into a single vca.
Loving the twisting sounds this makes , perfectly suited for my Epicyclus & Orchard music

What just happened?!
I think i just bought a WW2.1...
I was just reading up on some newish posts and reexamining your Simple Sampler(I have a YAKBAK that has been in my project drawer for 2 years now) not but minutes ago...
Then there is this blank spot in my memory... and suddenly I am staring at a PayPal confirmation...
