The third version of the app is pretty much ready to go to the store. Changes include a bugfix for attack transients, they were getting lost, plus the Principal Chorus on the Great, the Stopped Diapason  Chorus on the Swell, and the two Pedal stops (Bourdon 16 and Bassoon 16) have all been very carefully revoiced, partly as a exercise to finalize the tools I need to get the ‘real’ organ app out there in the next month or son. The revoiced stops sound gorgeous, and I will revoice everything and push out a 1.4 update during the Summer. Then I can just let it sit for a while and see what peo ..read more

Two keys at once, because I had not yet tested that. Powered USB hub into £12 'not Apple' USB camera connector, into iPad Air so you can see the screen - the iPod Touch would be invisible at this distance. Mind you, the screen still only has the stupid spaceship on it ..read more

Even better, on a 2012 iPod Touch, consuming less than 10% of the CPU, and quite happily synthesizing the organ while the GUI run's Apple's 'Game Demo' XCode project of the Phongy Spaceship. Great on channel 13, Swell on 14, pedals on 15. Next step, UI, then a trip to see Doug of Soundtestroom for a real demo, by somebody who can in fact play the piano. Update - consumes under 10% os 2011 iPad 2. Nice ..read more

So, during making of this pipe organ engine - actually way before that, when I was developing the Pi wavetable synth - I realized that pretty much anything that was a single, static wavetable sounded like a pipe organ. It’s just the way of things - not much else has an unchanging tone made up of a harmonic series. Your brain just goes ‘Yeah - that’s a pipe organ’. So I have decided to take advantage of that, and turn real instruments into pipe organ stops via wavetables, and that the first released implementation of the organ engine will be a completely fabricated set of stops, based on wa ..read more

I just built a much nicer-sounding reverb than the one in my M3000 mellotron to try to eliminate the nasty metallic resonances and make the pipe organ sound more ‘churchy’, and in turns out to not only sound lovely but is also computationally only about 1/2 as costly as my old one. Sweet. Demo to follow at some point ... UPDATE - demo here, of the organ integrated into the synths bundle, with the new reverb integrated as well. Yay ..read more

The underlying model is approaching complete. I revoiced all 12 of these stops today and they now sound very authentic indeed. Still to do - transients. Then the engine will be deemed complete, and I can lash up a UI, get it onto iOS, turn it into an AUV3, get it on sale, then start on the St Just in Roseland model. If you want to see this version - Bath Preservation Trust / Bath Museum of Architecture - on the Pi, I can arrange that, but to make it happen you will have to buy it on iOS in enough numbers. Once enough money is raised for the Bath Preservation Trust, I will make it available o ..read more

The pipe organ uses a version of ‘Trendline synthesis’, in this case more accurate would be ‘trendline voicing’ as the actual synthesis is wavetable trajectory. I have slightly extended the 4-parameter trendline method described by Pykett to add one extra feature - an individual harmonic that can be boosted or cut. And I found a great use for this feature - implementing ‘missing fundamental’ in the pedals. The lowest C on the pedals at 16’ is about 32.7Hz, very much below what my little studio monitors can reproduce with their 5” ‘woofers’. So I can’t hear it. Worse, it is there, and is using ..read more
