Obviously, if you spend $2000 on a multi track digital recorder you'll have a better system to play with than the $300 Zoom. Not a very fair comparison. By the way,
Zoom PS-02 has built in effects including chorus, reverb, flange, compressor, etc.
This is a very fair comparison considering the original poster stated "I was really just looking at
the PS-02 or the porta02 as a 'toy'... until I can afford an actual studio setup that would be able to produce the results that I am looking for. In the end, I am seriously looking at a Roland VS 880." Not to mention the fact that VS-880's are selling used for under $699 and often DO include excellent on board effects (as opposed to Zoom crap).
"you will NEVER get a decent recording out of it"
That's just wrong. Listen to some of the MP3s floating around that were mixed from the PS-02. They sound fine. [Also, 32khz is the broadcast standard. If you think FM radio sounds ok, then you won't mind the PS-02's sound.]
Let's examine why this comparison is wrong. Here are definite problems with the comparison between the PS02, MP3's, FM radio, and decent recordings:
1) MP3's and FM radio are adequate, not decent. Both formats are often played over computer speakers and car stereos in noisey environments. These playback mediums are crap and often don't illustrate the defects in limited bandwidth because they themselves have limited bandwidth. If you A/B a MP3 or FM radio recording with a CD quality or better recording, you WILL notice the difference.
If it is acceptable to record "adequate" crap, go right ahead. However, I guarantee you'll listen to your mix on a halfway decent stereo, or even decent headphones, and notice how much it sucks. You may get an adequate recording for a scratchpad, but you will not get a decent recording for creating a demo or even distributing to your friends.
2) The 31kHz sampling rate is compeltely inadequate for a decent recording. The 31kHz rate follows the Nyquist sampling theorem. Accordingly, frequencies of only up to 15.5kHz can be sampled without aliasing. To prevent this aliasing, filters must be employed to prevent any frequencies above 15.5kHz from being sampled. This results in an actual bandwidth of well below 15.5kHz. I hardly think (well below) 15.5kHz allows adequate frequencies to record a decent recording.
Here's a little experiment for you to prove the inadequacy of a 31kHz sampling rate to yourself: Run any CD through a graphic EQ or with a parametric low pass filter-type EQ. Adjust the EQ to eliminate all frequencies above 15kHz. A/B the EQ on with the EQ bypassed. Hear how crappy it sounds with all of those highs eliminated? That's what you're losing with a 31kHz sampling rate.
Thus, you will get a shit recording from the PS02. It's just a scratchpad.
