Hi,
Thank you so much Brody for taking the time to post this highly informative and useful reply which I truly appreciate which I'm sure will also benefit others having similar problems I'm experiencing.
Now you've pointed out about feedback it's so obvious and I'm aware of feedback but being new to recording studio kit it never occurred to me; Years ago whilst restoring vintage valve radios feedback was always a problem; connecting my engineering lathe and woodturning lathes to a single VFD drove me round the bend for ages until I found "cross talk" was the problem; I'd run the signal cables alongside the power cables which made the VFD do strange things; having found the cause I then used CAT 6 signal cable and isolated both the signal cable and power cable now both lathes and VFD are happy.
I'm sure you've solved my problems Brody; here's my studio and yes it's small; because of constant demands on my time the studio has been thrown together not only intending to use it for music but in winter to make a violin from scratch hence the benches and woodworking vice.

You really did get it right Brody because here's the problem; mic and monitors much too close together hence massive feedback which you described in detail.

A picture of the studio from the other end; my lovely wife does card making and crafting so I added this section for her where she can be seated in comfort by the laptop; mostly it's just me in the studio.
Now you've kindly given me the solution Brody I'll certainly have a go at sorting out the studio moving the kit around and another useful piece of advice you've kindly given me is to look for the dot on the mic which I wasn't aware of but with my luck I bet the dot is facing the monitor when I check.
Yes as you say Brody I've sorted out recording and playback using the Tascam which wasn't easy for a total novice but I'm stubborn enough to sort things out however long it takes; with your help I won't waste a great deal of time and effort in playing my violin directly to the monitors using the Rode mic I'll just buy one of the electromagnetic pickups you suggest; funds aren't a problem so I'll buy a pickup today there are lots on eBay unless there is a recommended pickup because sure as anything I can always buy the wrong item.
I'll isolate the Rode mic from the monitors; I can site both monitors at one end of the studio nearer the ceiling but allowing easy access for volume adjusting and the mic at the other end of the studio but I'll also take care to seperate the cables as much as possible; I've possibly bought the interface and laptop not really needing these for what I wanted to achieve but now I've got them I'm sure they'll both be useful especially the laptop which will allow more serious recording; I've a great deal yet to learn but I'm pleased so far with my progress; yesterday I enjoyed three peaceful violin practices; I'm obssessed with wanting to play Lara's Theme on my violin and the final practice yesterday I was delighted to play a decent section of Lara's Theme four times in a row with near consistency so I'm now also gaining more experience with my violins.
Time has been my biggest enemy in not having enough of it even though I've been fully retired 21 years; maintenance of our detached bungalow and gardens is very high placing demands on my time; after recent storms I ended up removing 15 very tall trees in just under two weeks working on my own in terrible conditions then other jobs followed; in order to read my "The Strad" magazines I take a copy with me whilst shopping; I visit Morrison's at around 7am then pop round to Aldi by around 7:30am where I enjoy a bit of peace and solitude sitting in the car until Aldi opens at 8:00am; last Friday as usual I parked at Aldi and was nicely settled starting to read the magazine when a car parked next to me although the car park had lots of empty parking spaces; nothing at all wrong with this but this particular car seemed to have twenty doors including the hatchback which the owner liked to keep opening and slamming closed; after a session of this he then wandered around a bit before repeating the door opening and slamming; I was just being selfish expecting a bit of peace.
The car door slamming set up my day very nicely indeed; back home I had a job to do this was to re-lay three loose very heavy paving flags but these were difficult to access due to foliage; it took ages and I finally completed the job thinking at last perhaps now I can get into the studio. Saturday WOW I was seated in the studio at peace with the world when my wife came in looking distressed; our neighbour was here asking if we'd seen her cat "Dudley" saying he was missing but she could hear a cat crying?
Our garage is beneath the bungalow and also I have access right under the bungalow so Dudley might have been locked in for a day; I checked but no sign of Dudley but standing to the side of our bungalow we could hear light crying and it was coming from under our feet; the pathway is hollow underneath this being flood defences; back into the bungalow and put on my working clothes then lift a flag to see Dudley staring at us looking terrified. I'd entomed the little lad who must have gained access under the pathway whilst I was mixing mortar; what a relief though he was safe; now I had the loose flag to relay which I didn't begrudge in the least; it was Saturday afternoon and I had just enough time to sort the flag out. Going down to the garage I couldn't help but notice the pigeons had made a huge mess all over the back and side of our car; choice here; do I sort the flag or car and it was already looking like rain; I covered the flag hole witb a sheet of plywood and washed the car so now this was Friday & Saturday without peace and Sunday too because I then relaid the flag; we've lived here for 35 years and even in retirement I have problems with time.

Relaying these flags was an horrible job but with my luck why not do the job twice. I felt sickened for Dudley.
Yesterday I really enjoyed the three violin practices and fingers crossed I'll now have more time to call my own; the hedges are trimmed the grass is cut; the trees are felled and disposed of; the garden bench is painted; the iron railings are painted; the car is washed; the gardens are weeded; the paving flags are sorted; the shopping is done; can I have a day off please?
A huge thank you once again Brody for your valuable help; I'll post with progress; now to sort out the studio at last before I'm wanted elsewhere.
Kind regards, Colin.
