A FM metallic bell'ish sound
8 voices polyphonic

mtyas 2016-11-25 12:43:01 UTC #23

A track done by using most of the last made sounds, very little processing (a bit of eq and a big Plate reverb on Aux).

Axoloti is really good at producing FM sounds (good old DX years all over again).

An accordion sound
7 voices polyphonic

I used this sound, converted into a MPE instrument and with a big delay, for this video (played using a striso board and one axoloti)

A Church Organ Patch
Paraphonic with built-in church reverb.

Available in the library:
Library/community/tiar/GM/020-ChurchOrgan-tiar.axp (26.9 KB)

"fb" controls the brilliance.
0 for a dull organ sound.
45 is optimal.

Here is a Dark Strings Patch
85 note paraphonic with stereo vib/chorus.
The modulation wheel introduces octave doubling

Available in the library:
Library/community/tiar/GM/052-Synth-Strings-2-tiar.axp

Basic and barbaric test of paraphony:

A western movie camp fire by night.

Library/community/tiar/GM/023-Harmonica-tiar.axp

3 octave paraphonic
Aftertouch sensitive
The modulation wheel controls the echo/delay

Simply play parallel thirds to get the wild west spirit.

Thanks @SmashedTransistors for these great patches, they sound very nice.
I was hoping to easily add pitch bend to them (for my own usage) but I can't see a way my limited brain can do it.
Keep up the great work (I like the saxophone too )

lokki 2017-01-18 19:24:22 UTC #29

i don't think pitchbend will be easy to add since these patches use a fixed oscillator bank...

SmashedTransistors 2017-01-19 00:04:12 UTC #30

Most of the original string machines used a single HF oscillator and frequency and octave dividers.

Oscillators - in the oscillator banks i coded at the moment - are as easily modulable as any other oscillators.
I already added vibrato inputs for small (multiplicative linear: " * (1+epsilon) " ) frequency deviations (see the Harmonica patch).

I can make up a solution for larger (exponential) modulations and add an input for that.

Hi @mtyas,

I added +-12 semitone pitch bend to Library/community/tiar/strings/052-Synth-Strings-2-tiar.axp

Pitch bend on chords is evil

Library/community/tiar/GM/031-Distortion-Guitar-tiar.axp
(beware of sound level)

I started this one to test the oversampling / downsampling / antialiasing objects I am developing.

This is a polyphonic patch that uses a common distortion, so the resulting sound mostly depends on the frequency ratios. 4th, 5th and 8ves sound smooth, other ratios will sound harsher.

The pitch bend is +- one octave
the modulation wheel induces vibrato
the aftertouch controls the distortion (gains and cutoff/res of intermediary filter).

The distortion is x2 oversampled. It is based on the classic scheme: sat -> high pass -> sat
The saturations are anti aliased soft clippers (differentiated polynomials and x2 oversampled).

I added a stereotypical ping pong delay.

small error in the Distortion-Guitar patch : "Object name O2 multimode svf m not found"

SmashedTransistors 2017-01-26 18:31:21 UTC #34

I forgot to add it to the repo. Sorry.
It should work now.

Library/community/tiar/GM/040-Synth-Bass-2-tiar.axp

A mono synth bass reminiscent of the late 70s.

lokki 2017-02-01 21:33:03 UTC #36

great! for typical glide and portamento bass synth stuff i would rather use something like this at the input:

then feed your adsr from gate2 to only retrigger on non-legato notes if you so wish

Polyphonic aftertouch

SmashedTransistors 2017-02-01 22:14:15 UTC #37

Thanks @lokki for this tip

I did not spotted the glide object in the math directory!

I've used a kfilter to mimic the behaviour of an analog keyboard.
Old analog designs have an analog Sample and Hold circuit that charges a capacitor through a small resistor
See the "Echantillonneur bloqueur / CV" block here:

These basic S&H circuits induce a systematic fast and "clicky" glide.

So I added your legato circuit just before my kfilter:

I like the way it can be controlled It really reminds me my analog synth.

lokki 2017-02-01 22:48:48 UTC #38

nice. if you also use the lru midi in object you get the following effect:

when you glide from one note to another and hold the old note it will bounce back to this old note once you release the new note. this is one of the key features in bass synths or in bass synth playing...(at least for me)

SmashedTransistors 2017-02-01 23:18:42 UTC #39

I'm not really satisfied with the envelopes when playing "bounce back"

In the case of a new note, i want a snappy sound : re-trigger the envelopes.
In the case of bouncing back to an old note, i want a smooth sound : no env re-trigering.

I try to figure out how to distinguish those two cases.

lokki 2017-02-02 07:36:03 UTC #40

ok, i see. so you want retriggering of new notes even if you play them legato? and only want to have smooth transition when you release a key and there is still one that is hold? i think for that you will have to write your own (or modify an existing) midi in object.
