200e

can you get higher frequencies using 291e in FM mode?
wikipedia about it:

The 291e also supports frequency modulation of each input which makes it
possible to build both simple and complex FM operators. The fm circuit of
the 291e is different than that of the 259e and 261e and less prone to
aliasing. Combined with a 210e, the 291e supports the following FM algorithm
constructs:

   - *M -> C* This is the basic FM operator, where the ratio of M and C are
   simple integers, usually N:1, but can be whatever you choose. The 291e can
   provide three such operators.
   - *(M1 + M2) -> C* A complex parallel FM operator (requires a 210e to sum
   the modulation signals). The 291e can provide three such operators.
   - *M1 -> M2 -> C* A complex series of FM operators. This requires two
   291e inputs.
   - *(M1 + M2) -> M3 -> C* A more complex series of FM operators. This
   requires two 291e inputs.
   - *M1 -> (M2 + M3) -> C* A more complex series of FM operators. This
   requires two 291e inputs.
   - *M1 -> M2 -> M3 -> C* Requires all three 291e inputs. This basic
   algorithm has numerous variations as M1, M2, and M3 can each be summed (or
   not) with additional modulation inputs.

Thus a 291e can be a powerful FM workstation independent of its filtering
abilities.
