Hi,

I know how I can make a hydrogen drumkit, But how do I make a good hydrogen drumkit?
Layered? how?
gain, pitch, fine?

Attack, decay, sustain, release???

cutoff , resonance?

random pitch?

Layered.
The use of differents samples to differents dynamic will help to make a more realistic sound.

It's what I think.

hiho,
--imo--
1. use high quality samples.
1.1 without noise.
1.2 without dc offset (reduce pops and clicks)
1.3 the sample end have to be zero to reduce pops and clicks.
1.4 peaks max 0 db, peak min -6 db do get the best resolution. h2 internal sound resolution (depth) is float between -1 and 1http://en.wikipedia.org/wiki/Floating_point .

2. try to short all samples to the possible minimum length. ( better performance )
3. if your samples have dynamic problems edit all important dynamics with an external editor like audacity ore what ever. than you don't need the h2 dynamic section.
4. if you work with layers all samples can also have the same maximum velocity peak between 0 - -6 db. hydrogen adjust the sample velocity and play the needed layer with the new computed velocity. so all layer can have the same max peak. this is important to use the maximum of resolution.
5. be car full with to abrupt transient's.
6. edit all samples with a minimum high-pass of 40hz to reduce bass babble.

good advice, though I don't understand all of it. Like what's a dc offset? What's a maximum velocity peak? A high pass of 40hz? You mean I can't use infrasound samples? Yamn!

I'm reworking a few custom drumkits with the new audacity. Being a bassist and not a very good drum programmer I deal with crosstalk in the lower frequencies a lot. Are there any other limitations in H2 you've discovered? (Not talking about bugs, my install works very well.)

For example, I have a dual 500mhz machine with 512mb ram running a variety of OS- Suse, 64studio, Ubuntu Studio. So far I've noticed that using all 4 effects on many long samples in a mix can crash the app, but my suspicion is that my computer is a wimp and can't do 20 pushups.

I've had sample lengths of 8 seconds work very well in a song. I know that is a bit unreasonable and ridiculous, but so is much of the music I compose.

This is still the best drum machine I've ever used. gigaprops to the dev crew. Ya'll rock the hacienda!

hiho, maybe my english produce some falsities. with maximum velocity peak i mean the positions with the maximum amplitude into a sample.
of course you can use samples with lower frequency's than 40 hz. but mostly you can't listen to so low frequency's. to get a more clear and transparent sound and to prevent damage the audio hardware it's very much better to cut this low frequency's.
dc offset is a little bit complexer. here a small link to general problems with dc offset. http://www.harmony-central.com/articles/tips/eq_dc_offset/.
hydrogen play a lot off small samples. sometimes more than 3 4 5 or 10 samples together. if all samples have positive ore negative dc offset the offset will aggregated. then you lose very much headroom.
the next problem is the ugly pop or click sound to the end of a sample with dc offset. e.g if the sample end with 10mv offset (-40 db) than you can hear the moment if the sample ends and the amplitude goes from 10mV to 0V with a short pop or click sound. if you play a simple 4/4 beat with 120 bpm maybe you can listen to 80 or more pops and clicks in one minute. uahhh ugly.

Ok, I got it now. If I normalize the sample before editing the sample returns to the proper dc offset and the pop goes away. I tried your suggestions out in Audacity last night and got excellent results. Thanks for the info.
