This is a very opinion-based question and likely to get closed by the adult-supervisors here. But meanwhile....
Has stereo equipment CHANGED in the last 10 years? Certainly. It is hard to find any area of technology that has not changed over time.
Has stereo equipment IMPROVED in the last 10 years? That is a different question. You could argue that ...
Ableton Live's M4L granular ensembles
MOTU MachFive has a granular module too
iZotope Iris, if you can stand the interface
For all three, press Record and start exploring.
Also, it's always a good time to challenge preconceptions of what "computer/tech sound" is.
With a lot of channels you can imitate a vocoder: You need to split the carrier and modulation signal into frequency bands as Internet Human stated. For each frequency band you need 3 tracks with the exact same filter setup for example for band 1 you chose lowpass at 100 hz and highpass at 50 hz. One channel has the modulator as its input signal, the other ...
S-Layer (and Reaktor)
Metaphysical Function, Skanner (also for Reaktor)
Camel Audio Alchemy ("the best sampler there is")
Perhaps even NI FM8 or Sytrus.
Too many ways to approach "computer sounds".
Synths can be great for this stuff, although depending on which program is used, I have at times had difficulty getting the sound to not feel "synthy". I think I mentioned this in a thread a while back, but I'm a pretty big fan of taking other recorded sounds and processing them with different plugins like GRM and Sound Toys to get the results I want. Often ...
Additive synthesis describes the process of combining (adding) sounds together to make new sounds, hence the term "additive". "add" ... you add stuff together.
Subtractive synthesis describes the process of making new sounds by removing elements of a sound through processing such as filters, hence the term "subtractive". "subtract" - you remove stuff.
The underlying sensor will be a piezo-electric pad which generates a voltage depending on the force presented to the pad. The generated voltage will then be converted to a midi note-on signal and an associated volume control level in the drum pads.
There are various online tutorials available that will show how these can be made using piezo-electric pads ...
The problem seems to be that you have connected a balanced mono output(XLR) to an unbalanced stereo input(3.5mm stereo jack).
You need a sound card that accepts two balanced line-level inputs(XLR or TRS). The Startech 7.1 only has a stereo line-level input(unbalanced), and two microphone inputs(Mic-level). This isn't a professional sound card.
I have ...
I don't know how much this helps, but I started out by making beats using flstudio, which has some cool visual plug-ins that make it easier to internalize the function of all of the different tools and effects, and applying them to a track that I made felt like it made learning about them even more satisfying, so I thought that was a great introduction into ...
If you're after something original then perhaps the obvious tools like synths and processors should take a back seat?
Try recording electromagnetic interference by hooking up a guitar pick up to a preamp and waving it (briefly and carefully) over all of the millions of electronic gizmos we all own. Makes some great sounds and won't damage anything if you're ...
I've used Absynth in the past for these types of sounds. Especially if you're looking for the musical/ evolving textures.
While probably too "standard" for what you're looking to achieve, I also really enjoy using Varun Nair's SigGen to create interesting telemetry elements
