'clap of luxury' has a randomly seeded patch generator. unless you turn the buttons in the lower left hand corner off before adjusting the patches, the params will return to their position when you trigger a note.
the params affected by the random seeding are also not quick to respond when they have been selected. i never figured out how to make the se "subcontrols" work appreciably, never used them again.
bong has a clap.

no, i see such things as bulk given that hosts already have sequencers. it uses a "mostly" GM key map fit to an octave and repeated across the keyboard, so it won't take much effort to translate existing sequences for it.

That's a pity because not all hosts have sequencers for example Audiomulch and a drum machine without a sequencer seems to ruin somehow the whole idea of a drum machine to me.

yeah. i feel the same way about using hosts that don't have sequencers to compose rhythms 
there's always wrappers like eXT.. never heard of it having problems with audiomulch.
developer's journal.. for the purpose of providing one example of how "things people pay for get built".
spent nine days on toms (days typically involve 4-12 hours work with an average of 6 hours), think i finished the emulations by day 6, and the last two days were spent fiddling with nonlinearities to add harmonics to a generic "blip" tom algorithm. the last day i seriously spent about six hours selecting between two finished solutions from the day before. (ultimately i split the "blip" algorithm into two algorithms.. one with a pronounced attack for lower pitches, the other without for high pitched laser effects).
during development of the harmonics solutions i started working on the roland "representative swing type vca" mentioned earlier.. which was convenient because the next thing to do is an emulation of the 808 rim, which uses that. i'm modeling the waveform, not the swing vca circuit..
development is development.. many projects are easy to build once conceived of.. there are seriously entire synths that can be coded in an hour or two. it doesn't have to take a long time, and, hopefully as i've made apparent, 6 hours of waffling to select between two options isn't a sign of high geared productivity.
overall, hardly exciting or prestigious.. these toms are generally an exponentially decaying sine with some lowpassed noise..
optimised the softclipper algorithm in my dsp notes by removing a multiply.. here are some optimisations with different thresholds and limits. efficient, but the long version is easier to understand
if (o1 > 1.0) o1 = 3.0 - 4.0 / (o1 + 1.0);
if (o1 > 1.0) o1 = 5.0 - 16.0 / (o1 + 3.0);
if (o1 < -1.0) o1 = 16.0 / (3.0 - o1) - 5.0;
if (o > 0.25) o = (o - 0.25) / (o * 3.0 + 0.25) + 0.25;
else if (o < low) {o = low - o; o = o / (o * -5.0 - 1.0) + low;}
stuff that will make it into the percussion synthesis pdf.. some, many of the nonlinearities (waveshaper, same thing) are dynamic, loud sounds will have more harmonics proportionally (simple case = clipping). this results in decreasing harmonic content with the decay and is an easy way to brighten simple waveforms and produce a "realistic" impact.
the ones i ended up using aren't dynamic or aren't as dynamic (i want similar timbre with velocity variation) - but they sure sounded good. a simple sine pitch drop can sound quite acoustic as such (used polynomial waveshapers, up to 7th or 9th good for sinusoid toms). fairly basic, but useful to be emphatic for beginners

continuing the early advertising campaign for this product,
here's a postcard of the moment of joy..
if you build an 808 rim emulation with 2 sines and clip the higher at 0 and some +value, you'll get a fairly predictable superimposition of one osc on another.
this image is one step past that.. it doesn't look that close viewed casually, the higher pitched osc still has a way to go, but there's a fundamental step that, should you get up to the precedent stage, you'll immediately appreciate
secret for the time being, beyond that this step is not realisable if you use a wavetable or phasor based oscillator.

if i was less lazy and prepared an eg. file of the non-differenced rim it'd be more appreciable the last post is a note to future emulators (there's not too much on the 808 rim online).
i don't know if that specific piece of information will make it into a percussion synthesis pdf/presentation as it's more "roland/circuit wierdness" i guess. but definately when i apply myself to constructing such a document, it will be a better read than the stringing and occasionally evasive posts in this thread
yesterday evening was one of the yoga sessions spent making minute adjustments to source and repeatedly going through a mechanistic ~45 second process of opening and closing various apps to translate the output into comparable data, hundreds of times. there are days like that with emulations
one falls asleep going "i can audition this snare drum a few dozen more times.."

closer.. (still work to be done, eg. the spike occurence).
the stuff i'm seeing may never have entered the minds of the analog engineers or other methods of digital emulation. (i guess reverse engineering the waveform.. since i only have the dr110, is naive emulation) it's weird and informative.. i get (at least in part) how the frequencies are ~"smushed" together on some of the instruments.
if you look for an "overall" contour, the lowest freq is clearly visible in the decay, but the "overall" contour at the beginning of the file has a slower rise and fall to it, exhibiting smushiness.
anyway.. fun puzzles. thought about making a game.. given a complex waveform of up to 10 sines (10 game levels) how rapidly can you visually analyse it in the least number of adjustments..
sell it

did something stupid today... looked at one of the popular emulations..
if you use a commercial drumsynth you like, may i ask you to post a sample of the rim, at it's most emulative, "default" configuration as i'd like to do some dick measuring.
i try to leave people with a right to their own choices in life. i may have to show off some when it comes to a digital filter for hihats and cymbals. not because i have an ego, but because if people are going to pay that price for that quality, i am bound by duty to engage in the difficult and painful task of securing their attention for long enough to present an alternative.
filters for hihats, people, oversample.

did something stupid yesterday..
later i found some other demos of the same drumsynth that sounded great. first group of demos i heard hats sounded like a box of cornflakes, probably a higher noise/osc mix than i'm accustomed to for that hat. higher mix of superlatives in their product description too. i'd still like to have a good look at their rimshot.
the digital bridged T osc structure also works as a bandpass filter. blue = low gain and high gain, orange is a SV 12dB bandpass.. (cutoff was slightly different when image captured) notice the crap rejection bands on the BT (and the dc). several analog drum sounds exhibit this f.r. curve, which is why if you use a generic bandpass, eg. your snare will have less high freqs and sound less snappy.

i think just about every drum machine sample i've looked at exhibits power supply harmonics in the signal.. and also exhibit the cpu/sequencer clock pulses in the audio, at a lower level.
it's more conspicuous when A/Bing an emulation (ponders how this manifests in sequences.. whether it's phased by some voices and cancels on some trigger combinations..)
maybe an effect idea.. envelope follow the audio, mix in psu signal.. oh goody, 60hz, my favourite..

internet dumped my post. retype short version:
almost finished hats c. june 15th, rebuilt from scratch two days ago after pondering oscillators. glad i did, worked out well. why post samples, there's like maybe 10 people who would recognise a dr110.
wrote about observations of psu harmonics, how eg. 240hz makes it into the highpass on the hats to.. ooh, around -20dB of the peaks!
also wanted to guarantee readers that my dsp is surely the most enlightened in existence, if not the entire cause for existence itself. i'm anxious to wrap it up smart looking and milk $250 a head out of some confused bastards as is my divine right, heralded by angels and, woah, there's that unicorn again. all the glossy magazines agree, and so do all the banks in the entire world and all the ninjas too.
