Hey list,<br>

"Compared to the "Analog" series devices from Elektron, there are a
couple of changes.
<ul>
<li>The new "encoders" are actually potentiometers (probably
sin/cos). That's very clever.</li>
<li>The "Analog"-series devices had a USB isolation to avoid
having a ground loop when the device is connected to a computer
and an audio interface. The USB isolation chip was removed.
Instead, there is now an isolation between the analog side and
the digital side of the circuits. The power rails and grounds
for the analog and digital sides are entirely isolated. That
way, ground loops are still prevented, but in addition digital
noise is kept away from the analog circuity much better.</li>
<li>The magnetic NVRAM that was used in the "Analog"-series
devices was removed (probably too expensive and too small - the
largest available on the market is currently 16Mbit). Instead,
they use a 1Gbit DDR2 SDRAM powered from a Supercap. So,
effectively you get the "persistent" memory (no loss of data
when power-cycling, even without saving your project) but it
porbably won't last 20 years like the magnetic NVRAM</li>
<li>The new switches are computer keyboard switches from Kailh -
apparently that is a "Cherry MX" clone.</li>
<li>The type of OLED display is unfortunately not visible without
desoldering it from the pcb.</li>
<li>They are still using a coldfire processor. To my
understanding, that is pretty comparable to the higher STM32F7
devices (maybe a slightly faster) but interestingly the SRAM on
those is only 64kB."</li>
</ul>
