ARP Avatar upgrades and service (320 words) |
 | This frequency response upgrade is similar to the 2600 filter upgrade extending the cutoff frequency range from 11khz to 28khz. |
 | This mod installs a switch in your Avatars ADSR section that engages the turbo mode speeding up the time constant on the ADSR to attain 2600 type percussive envelopes. |
 | Stock Avatars have their portamento circuits hardwired to the guitar section. |
| ARP Odyssey (1926 words) |
 | You see, ARP had pretty much copied the famous Moog 'ladder' filter in their ARP4035 filter design and this was used in early versions of the the company's 2600 modular synth. |
 | ARP were well aware of this but could not be seen to copy Moog (again!) and so they devised a new performance mechanism which they called "Proportional Pitch Control" (or PPC). |
 | ARP's market was dwindling under the onslaught of cheaper (but capable) synths from Roland, Yamaha and Korg as well as new models from old rivals Moog and whilst the competition were introducing new synths with ever more features and functionality, ARP were pretty much standing still. |
