Synth Rorschach #38

This one is a bit of a reverse synth rorschach. Usually it's a non synth item that reminds me of a particular synth or synths. When I saw the small thumbnail for this one, my first thought was what the heck is a pacifier doing in my synth feeds?! I guess it could be a little game piece or top as well. Steampunk eye piece? Synths are messing with my mind!.. That and it's a bit early for me. But no, don't use this as your pacifier, I'm guessing it's not food grade plastic.

YAMAHA DX7 SUPERMAX

Published on Jan 11, 2015 jerry dibella

"This is a little tutorial/demo of how I mount my SUPERMAX expansion board for the YAMAHA DX7 mk1.
The SUPERMAX card is fantastic, I bought it on the Ebay, from France, and it adds some great features to the DX7, you have 8 bank of memory allocation (256 user programs for save your patches), you have also a delay effect, stack function, detuting functions, midi functionality, a fantastic arpeggiator and a patch creator too! It has 64 preset on, that shows the new ability of your Supermax'd DX7...the first time it is a little strange, but then you start to know how it goes...it has balls! Yooooo!

Questo è il filmatino che ho girato mentre montavo per la prima volta la scheda d'espansione SUPERMAX per la mia Yamaha DX7. La scheda l'ho trovata su Ebay, in Francia, ci ha messo un po' ad arrivare, ma ne è valsa la pena...la DX7 ora è davvero potente...arpeggiatore fantastico, delay, funzioni di stack, midi, tuning espanse...in più ha addirittura un patch creator con cui creare i propri suoni e altre funzioni che stò scoprendo poco alla volta. Consigliatissima! Presto cercherò di fare un video sulle funzioni aggiunte! Ciao!"

CMOS 1-bit FIR Filter

Published on Jan 10, 2015 Jacob Watters

"A silly experiment making a FIR filter with CMOS chips.
More info here: http://www.jacobwatters.com/blog/cmos..."

"The idea for this experiment came while chatting with some other synth builders about digital FIR filters. One person had previously mentioned that a Lunetta delay circuit I had made was similar to a FIR filter. It used shift registers like a bucket brigade to delay pulses from a square wave Lunetta oscillator. The taps were divided by increasing amounts along the delay line. The idea was to emulate the decaying level of feedback (echo) in a bucket brigade delay circuit.

So I figured I would give it a try again, but this time with the intent of emulating a FIR filter.

Not Technically a FIR
Before getting into the details of this project, I have to make some disclaimers.
This is an emulation of a FIR filter, and not a replacement.
This circuit is entirely impractical. There are far easier analog methods to filter sound.
This circuit only works with pulse waves. Other waveforms are converted into pulse before being used.
This circuit is noisy due to the low sample rate."
